Essentially any object can be turned into a light source. 

- But what about efficiency? Although OLEDs are not yet on the same level of LEDs regarding life time or efficiency, their evolution is preceding strongly. In 2009 OSRAM 

presented the OLED light source “ORBEOS” as the first qualified OLED panel – it is especially suited to applications in the premium segment such as 

architecture, hotels and catering, offices, private homes and shops. The recent breakthrough came with the evolution of the luminaire PirOLED – the first step 

towards an independent OLED luminaire family. 

- Now it’s time to start the ignition sequence – to augment the high design aesthetics with functional illumination. The company took an important step by 

installing the first pilot production line for OLED Lighting in the city of Regensburg. It will soon start running and will lead the manufacturing processes towards mass OLED 

production. Ready for take off ?

02:15 pm R2R Printing Platform (Seed-financing) 

Mr Ankur Sharma, 

Delftronics, Netherlands 

Flexible memories, displays and batteries are out of various labs but the absence of high speed low cost transistors on plastic is preventing realization of those creative 

products that the multi-billion dollar “flexible market” is eagerly waiting for. At Delftronics, we are channelizing our focus (vision) towards an innovation 

enabling a roll-to-roll (R2R) process for printing high speed, low cost electronics. Such a fabrication technology will enable economical realization of various applications 

including large area flexible sensors with wireless communication modules and wearable displays with image, data and power transmission capabilities. An interesting 

product could be a rollable-mobile phone with an OLED display. At Delftronics, high speed thin film transistors are made in silicon crystals by printing 

“silicon-ink”. Despite using the printing technique, our innovative process offers a small feature size and high alignment accuracy between different layers, 

which are indispensible for realization of high speed thin film transistors. The Value Proposition is further strengthened by the fact that the process is fundamentally 

“ink-independent” and hence other inks and materials could easily be used, such as inks of metals, organic and metal-oxide semiconductors. Energy and 

material usage in the entire process is much lower than the conventional vacuum process and we continue to strengthen this core “green” approach of our IP. 

At Delftronics, we aim to create a complete “R2R printing platform” that would enable realization of high speed flexible electronics at low cost. Currently, our 

research is being funded by the STW Valorization grant- phase 1. In the next 2 years, we aim to baseline the printing process and create the blue-print of the R2R process. 

With our research know-how, motivation and partners coupled with smart investments, we believe that Delftronics can create the manufacturing backbone of the flexible 

industry in a period of five years.

Dr David Corr, 

NTERA, Limited, CEO, Ireland 

The Printed Electronics industry is making steady and good progress. Materials and processes have been developed as discrete components or technologies now 

available as part of the nascent toolkit needed by Original Design Manufacturers to design into products. However, with few tangible examples of products that designers 

can utilize as reference concepts, progress to the next evolutionary stage of Printed Electronics has not been as rapid as desired by the industry and the market. NTERA, 

leveraging its proprietary NanoChromicsTM display technology, a comprehensive and practical ecosystem of commercial partners, and internal design knowledge, is 

evolving to meet this challenge. NTERA has completed several system-level product/prototype designs incorporating NanoChromics display technology and is now well 

positioned to offer its customers full, turnkey solutions including inks, device and system design specification, printing, and application integration. With this level of product 

and service offering NTERA can be considered as an ODM, offering direct partnership with OEMs seeking to adopt printed electronics innovations within their product 

lineup. 

In this presentation, NTERA CEO, David Corr, will outline the rapid progress made by NTERA in the relatively short-time (three years) the company has been solely 

focused on Printed Electronics. Charting this progress, the presentation will illustrate how the company has successfully grown a strong network of partnerships, acquired 

early customers, and continues to successfully design future products for OEM around its technology - while incorporating complementary printed electronics technologies 

within these designs. The presentation will demonstrate several of the form factors emerging from these systems integration activities and how, with the emergence of 

these form factors, the company is moving rapidly to scaled commercialization of its products.

03:15 pm Printed Plastic Solar Power for Emerging Markets (B-round) 

Dr Simon Bransfield-garth, 

Eight19 Ltd, CEO, United Kingdom 

Eight19 is developing a new generation of printed plastic solar cells, using organic photovoltaic (OPV) technology. Based on work pioneered by the internationally 

renowned team at Cambridge University, the company focuses on high speed, low cost manufacturing techniques to create lightweight, non-toxic, flexible solar films. While 

solar power is well known for large-scale deployments connected to the electrical grid, a new breed of high volume applications is emerging for self-powered consumer 

products. The flexibility, low weight, robustness and ease of manufacture of printed plastic solar cells makes them ideal of these applications. The off-grid solar market is 

focused on emerging economies with an abundance of sunshine and a burgeoning demand for energy. Volume opportunities include lighting, refrigeration, pumping and 

mobile phone charging. In contrast to on-grid electricity, the cost of the existing power can be very high. For example, according to the GSMA, some 500M people 

worldwide have mobile phones but no mains electricity and spend as much as $36/year to charge their phones. Even with conservative estimates on pricing, the mobile 

phone charging segment alone represents a $2-3Bn market for photovoltaics. Similarly, in India, the number of solar lamps has grown from 500k in 2009 to over 1M in 2010 

and the Indian Government is the first to include stand-alone solar lights as part of their national solar subsidy program. Eight19’s “roll-to-roll” printing 

techniques create environmentally friendly, low cost product ideally suited to these high volume consumer applications, where the cost, weight and fragility of traditional 

solar solutions limit the rate of growth of the market. Eight19 is headquartered in Cambridge, England and concluded a £4.5M Series A from the Carbon Trust, 

Rhodia SA in September 2010. The company will be seeking Series B funding in 2012. For further information, please visit www.eight19.com

Active Paper makes graphics appear on empty paper. These printed hidden features can be used as interactive elements in combination with static graphics and/or as 

advanced sensors and indicators. Thereby Active Paper is a platform for a range of novel paper based products, such as medical diagnostics devices. Our first customers 

will be consumer brands, to whom we sell marketing materials with changing graphics. These products are quick to commercialize and act as stepping stones to future high 

value added applications. Our ultimate aim is to commercialize Active Paper as a platform for easy to use point of care (POC) tests. We’ve already demonstrated 

first medical diagnostics tests in lab scale. The platform will dramatically expand product design possibilities for diagnostics companies. Our platform can also cut 

production costs dramatically. Cost effective production coupled with new opportunities for design will enable everyday monitoring of e.g. health, well-being or the 

environment. This will also bring diagnostic features into new higher volume markets, such as consumer goods. Starting with simple products allows our partners and us to 

build a basis for industrial scale production, which can be leveraged in developments toward POC. Marketing products bring us strong operational income before 

introducing Active Paper to the diagnostics markets. Our products are based on Active Paper technology developed by VTT Technical Research Centre of Finland. The 

main advantages of the technology include: (1) Novel design possibilities and ease of use. Active Paper brings added functionality combined with traditional graphical and 

molding capabilities of paper. (2) New markets. Our technology enables customers to expand their products with value added features and take them to completely new 

business fields. (3) Cost-effective solutions (a) cheaper materials (b) streamlined production process (4) Sustainable solutions. Paper as a biodegradable natural material is 

a splendid substrate for multiple applications.

Printing Technologies (11:30 am - 01:20 pm) | LOCATION HARMONIE D / LEVEL C2 

11:30 am Optimized process for S2S and R2R screen printing of conductive structures for plastic electronics applications 

Mr Eric Rubingh, 

Holst Centre, Senior process engineer, Netherlands 

Requirements for printed conductive structures within plastic electronics applications, such as electrode grids in OLED and OPV devices and HF antennas and circuitry in 

smart packaging applications, are challenging. A deposition process, capable of small feature sizes with high quality line formation and sufficient deposition amounts to 

reach the required conductivity, is needed. As speed and cost of processing is important, we chose for a single step R2R compatible screen printing process, capable of 

sub 100 µm feature sizes with high deposition amounts, and combined this with an in house build R2R photonic sintering tool. Although inkjet and flexo printing both have 

their own benefits and can easily reach the targets set for feature sizes, they both require either a multi layer print approach or an additional process to reach the required 

conductivity for the mentioned applications. 

In this paper we present results of a study on optimizing the print quality of both S2S and R2R screen printing of commercially available nano and micron particle silver 

pastes, using both oven and inline photonic sintering. The traditional way to achieve feature sizes of sub 100 µm with flatbed screen printing is using high mesh number 

woven meshes. However, the disadvantage of these woven meshes is the decrease in deposition amount with increasing mesh number, resulting in less thick lines and 

thus lower conductivity. By using an optimized electroformed nickel mesh technology we were able to increase the amount of deposited material, with better print quality 

and dimensional stability compared to ?standard? woven mesh technology. The knowledge obtained with the flatbed screen print experiments was used to facilitate the 

step towards R2R printing with a rotary screen print tool, using the same electroformed meshes and materials as with the flatbed screen print experiments. Finally we 

compare obtained results with the requirements for several applications.

12:00 pm High Precise Machine Directional Register Control for a Multi-layer Roll-to-roll Printed Electronics 

Dr Hyun-Kyoo Kang, 

Konkuk University, Post Doc., South Korea 

The rising demand for the fabrication of flexible electronics using roll-to-roll technology exposes the abundant challenges of conducting low cost highly productive printing 

trials. Discrete printing and single roll printing were applied for printing of electric circuitry. But productivity of these methods is lower than the productivity of a roll-to-roll 

continuous printing method. 

Printing cylinders between unwinder and rewinder have variations of phase. A strain of substrate passing the printing cylinder is varying due to an effect of inertia, 

temperature change in dryer, etc. The variation of strain of the substrate is a major factor of a machine directional register error in a multi-layer printing. Therefore, the 

variation of strain should be controlled to minimize the machine directional (MD) register error in a successive roll-to-roll printing. 

Brandenburg derived a model of the MD register in a first-order differential equation using an equilibrium equation of mass which is transported by a cylinder. A 

non-interacting control method between the tension and cut-off register error was also proposed. Yoshida proposed a MD register controller to compensate for a 

downstream register error caused by upstream tension fluctuation. 

The MD register is a function of strain of upstream and downstream. The upstream tension could generate MD register errors in a downstream span. So, it is necessary to 

reveal the correlation between tension and MD register for developing a precise MD register controller considering the strain. In this paper, modeling of MD register was 

derived considering the tension of substrate and phase of printing cylinder. The MD register model was validated and verified by numerical simulation and experiments by 

direct gravure printing machine. And a PID controller for MD register error was proposed and verified by experiments. The results can be used for design of MD register 

controller for precise roll-to-roll printed electronics.

12:20 pm UV Lamp Design to Optimise UV Curing Processes in Printed Electronics 

Ms Dawn Skinner, 

Fusion UV Systems GmbH, Process Development Manager, Germany 

UV curing is a technology that has grown and diversified widely over the past 30 years; from its early use in printing and wood coating through to applications in coating 

industrial plastic components, bonding and coating applications in medical devices, glass coatings, protective coatings for optical fibres and specialised coatings on flexible 

films, just as examples Its success has been driven by improved coating performance, fast cure speed, small compact units, economical use of energy and low heat impact 

on the coating and substrate and, the potential for 100% solid coatings and adhesives. To meet the demands of high volume production with lower manufacturing costs, the 

processes for organic electronics must be automated leading towards roll-to-roll applications. Additionally, many of the substrates used in printed electronics are heat 

sensitive films, so low temperature curing of the coatings and inks is required to prevent distortion of the substrate. The rapid cure of UV inks and coatings and the low heat 

impact of the process are key motivating factors for the interest in UV curing from the printed electronics manufacturers; with opportunities for UV curing in applications 

including , encapsulants, barrier coatings, conductive inks and coatings, anti-reflective coatings. To achieve the best possible properties of a UV cured coating material, it is 

essential to optimise the interaction between the chemistry and the UV lamp system. This paper will look at the issues of correlation between absorption characteristics of 

the coating and emission spectrum of the UV lamp, as well as the influence of UV energy, irradiance and temperature on the UV curing process. In addition, the paper will 

review the design of UV lamp systems and the installation of the curing units into manufacturing lines to optimise these key parameters. 

12:40 pm Polymer Vapor Phase Deposition (PVPD®) as key-enabling technology for advanced polymer thin films 

Mr Juergen Kreis, 

AIXTRON SE, Senior Department Manager Business Development, Germany 

PVPD? utilizes a carrier-gas enhanced vapour phase deposition approach for in-situ polymerization and layer formation of functional polymer thin films. 

Compared to conventional solvent-based polymer deposition, PVPD realizes in-situ formation of polymer films in an all-dry-process, intrinsically avoiding respective 

limitations of a wet-process. Integration of AIXTRON?s close-coupled showerhead (CCS®) technology ensures high deposition rates and free scalability of the process. 

These advantages recommend PVPD for advanced and novel applications, where functional polymer thin films contribute to the overall performance with optimized 

properties.

01:00 pm e-LIFT: a laser printing technology for organic electronics 

Dr Philippe Delaporte, 

CNRS - Mediterranean University, director of research, France 

The development of a simple process allowing the deposition of a wide variety of materials, with high spatial resolution is of great interest for the manufacturing of future 

smart organic electronic devices. The objective of the e-LIFT European project (FP7) is to demonstrate the integrability of a new laser process in the industrial world of 

electronic device manufacturing for the localised deposition of organic and inorganic materials under liquid or solid format. 

The optimization of the Laser-Induced Forward Transfer (LIFT) process has been performed during the first step of the project, and the potential and limitations of this 

technique will be presented. The LIFT process has then been used to print the building blocks (sensors, OTFT, OLED) of future organic electronic devices. We 

demonstrated the direct laser printing of photosynthetic material (thylakoid membranes) onto low cost non-functionalized screen printed electrodes (SPEs) for the 

fabrication of photosynthesis-based amperometric biosensors. We performed successful printing of polymers layers on surface acoustic wave (SAW) sensor structure by 

LIFT, leading to sensors with sensitivity for selected polymers down to 5 ppm. Functional OLED pixels have been printed by LIFT using MEH-PPV based structures which 

reach almost the same efficiency as pixels prepared by standard methods. Finally, Organic Thin Film Transistors (OTFT), with mobility of 5.10-3cm²/V.s using PQT 

semiconductor, have been printed. 

The results of this project will pave the way to the definition of a laser printing prototype together with reliability and productivity considerations.

02:30 pm Organic and hybrid thin?film transistors with novel architectures and high performance 

Prof. Bernard Kippelen, 

Georgia Institute of Technology, United States 

Over the last decades, organic thin?film transistors (OTFTs) have made great progress. The field?effect mobility in OTFTs has improved to a level where organic 

semiconductors compete with amorphous silicon (a?Si). However, an advantage with organic semiconductors is that the performance levels of n?channel and p?channel 

devices are comparable which is important for the design of complementary circuits. Despite these advances in field?effect mobility, long?term environmental and 

operational stabilities are still two major issues before OTFTs can be commercialize and realize their fll potential. In this talk we will discuss the performance of OTFTs 

based on bi?layer gate dielectrics. In particular, we will report on devices fabricated from solution processed organic semiconductors with a top gate geometry. Such 

devices show an average mobility value of 0.39±0.16 cm2/Vs and operate at voltages below 8 V. These devices do not show any significant degradation in mobility 

nor change in threshold voltage after 20,000 multiple scans, after a 24 h constant dc bias stress, or after exposure to air for over seven months. We will also report on 

hybrid organic?inorganic complementary inverters composed of pentacene and amorphous InGaZnO for p? and n? channel thin?film transistors (TFTs) fabricated on 

flexible polyethersulfone substrates. We will describe a new co?planar channel geometry for the realization of such transistors and complementary inverters wherein n? and 

p?type channels are horizontally distributed with different channel widths to achieve balanced operation. Using this geometry, we could demonstrate high performance 

ambipolar?like transistors consisting of amorphous?InGaZnO (mobility of 10 cm2/Vs) and pentacene channels (mobility of 0.3 cm2/Vs) with performance parameters 

comparable to those of unipolar transistors.

03:00 pm Submicron organic thin film transistors fabricated by UV nanoimprint and self-aligned photolithography 

Dr Herbert Gold, 

JOANNEUM RESEARCH ForschungsGesmbH, Austria 

The miniaturization of organic thin film devices is a key issue for enhancement of integration level and switching speed for future applications in large area printed organic 

circuits. In this study we report on a novel fabrication method for organic thin film transistors with channel lengths of several microns and down to the submicron regime. 

In a first step the aluminum gate electrodes were structured by residue free UV nanoimprint lithography [1]. For the dielectric layer a UV-cross linkable gate dielectric 

structured by photolithography, was used. The gold source and drain electrodes were structured by self aligned photolithography [2] performed by backside exposure 

through the micron and submicron gate electrodes. Finally, thermally evaporated pentacene was used as organic semiconducting layer. The contact resistance and the 

pentacene growth were optimized by a UV-ozone pretreatment of the gold electrode and the dielectric layer [3]. 

The overlap of the gate and source/drain electrodes can be minimized by optimizing the exposure time for the backside exposure as demonstrated by Transmission 

Electron Microscopy. The devices show an excellent behavior in terms of leakage currents and hysteresis effects. Fully functional small channel OTFTs based on n- and 

p-type organic semiconductors were fabricated on glass as well as on flexible substrates. The low parasitic capacitance of the devices enables new applications of organic 

devices with transition frequencies up to 400 kHz.

03:20 pm Measurement, analysis, and modeling of 1/f noise in pentacene TFTs 

Mr Hongki Kang, 

UC Berkeley, PhD student, United States 

The use of organic TFTs has been suggested for low-cost and large-area applications such as RFID and various types of sensors. To date, most research has been 

focused on performance and stability optimization of the same. However, particularly for sensing applications, it is equally important to know how immune OTFTs are to 

unwanted noise signals because typical OTFT current levels are small and their operating frequency range is typically low, such that 1/f noise is dominant. Therefore, it is 

crucial to understand the mechanisms underlying low frequency noise (LFN) in OTFTs and to develop a model to estimate the noise accurately. Here we present 

experimental results of the unique LFN characteristics in OTFTs with comprehensive mechanistic analysis and modeling using a unified noise model. 

For more than four decades, 1/f noise in conventional MOSFETs has been studied intensively, and it is generally believed that there are mainly two dominant sources of 1/f 

noise ? fluctuations in the number of carriers and in the carrier mobility. In previous work on LFN in OTFTs, there have been debates about which mechanism is more 

applicable to OTFTs. We conducted drain current noise measurements for pentacene-based OTFTs having different grain size, film thickness and operating region. From 

our experimental results, we conclude that carrier density fluctuations due to trapping/de-trapping of carriers by/from traps in the semiconductor are the dominant source. 

The effects of semiconductor grain size, semiconductor film thickness and operating region on LFN are presented. 

We also show that the unified noise model which is analytically derived for conventional MOSFETs can be applied to OTFTs with a notable feature which reveals that there 

is an additional mobility fluctuation induced by acceptor-like traps in the semiconductor.

03:40 pm Dynamic Characterization of Charge Injection and Transport by 

Mr Jack Lin, 

Tokyo Institute of Technology, Japan 

Semiconductor devices using organic materials, such as thin film transistors, light emitting diodes, and solar cells, have attracted a lot of research and commercial interests. 

The importance of basic research on the injection, accumulation, and transport mechanisms has also become more recognized to understand and improve the device 

performance. This paper introduces some enabling technologies that allow us to gain better understanding of the working mechanism of organic field-effect transistors 

(OFET), especially in the transient state. 

Direct imaging of carrier motion in OFET has been realized by the time-resolved microscopy optical second harmonic generation (TRM-SHG) technique, where the SHG 

light intensity is proportional to the square of the local electric field. The time resolved measurement was achieved by varying the delay time of the laser pulse in relation to 

the applied voltage precisely. By selecting the appropriate wavelength, the electric field induced SHG can be used to selectively probe the specific organic material of 

interest in complex multilayered systems. In this paper, we show results of carrier propagation in pentacene OFET obtained by TRM-SHG. Furthermore, contact resistance 

was also investigated by the potential drop which was directly evaluated from SHG. 

In combination with the electrical time-of-flight technique and impedance spectroscopy, along with conventional current-voltage measurements, it is possible to investigate 

the transient-state and steady-state behaviors of the OFET. The difference between these states is attributed to the filling of traps. Further study of the trapping states have 

been carried out by partially charging the gate-semiconductor interface (partially filling the traps) and investigating the device?s temperature dependence. 

Additionally, we introduce the newly developed technique to use time-resolved SHG for evaluation of carrier injection, recombination, and exciton generation processes in 

organic light-emitting diode and organic solar cells.

05:40 pm MetaPaper ? Cellulose sheets to filter electromagnetic waves 

Dr Guy Eymin Petot Tourtollet, 

Centre Technique du Papier, Director, France 

The paper and board industry is undergoing changes with the increase of the production capacities in Asia or in Eastern Europe. As a result, this imposes to a specific 

sector of the industry to turn to higher added value products. Among them, we have proposed to work on a key-concept to perform selective anti-Wifi or anti-GSM papers. 

As a mater of fact, the wireless communication technologies are in full expansion and this changes our environment which is surrounded by a multitude of electromagnetic 

waves (mobile phones, Wifi, WiMax, Bluetooth, RFID?). There is a need to filter some of the latter for individual and material protection but also for data security. For 

example, theatres, hospitals must remain « quietness » electromagnetic areas; some electronic systems requires protection against degradation or malfunctioning. Data 

security is also an important application, particularly for companies which use Wifi networks. A physical protection is the best protection against hacker. 

An efficient protection solution is the Faraday room but it is highly expensive, not easy to implement and it blocks all radiations. Cell-phone jammers exist but they do not go 

in the electromagnetic « quietness » direction. 

We propose a paper material functionalised to ensure selective frequency filtering. Electromagnetic waves are either disperse or reflected by it. It has the well known 

qualities of paper, such as low cost, renewability and it is a recyclable resource. This technology has been implemented thanks to printed electronic techniques. It can filter 

both Wifi and GSM frequencies at the same time, or only one frequency. Attenuation up to 30dB has been experimentally reached. This application is generating numerous 

high-added value products.

Sensors and Systems (11:30 am - 01:20 pm) | LOCATION HARMONIE E / LEVEL C2 

11:30 am Roll to roll printable technology platform consisting of electrolyte-based components 

Dr Peter Andersson Ersman, 

Acreo, Research Scientist, Sweden 

A lot of effort has been spent on developing components in the field of organic electronics. Some of the components have shown excellent performance and also 

printability. However, printed electronics has not yet reached the market. One reason for this is that the integration of components into useful products has proven more 

challenging than expected. One of the major challenges is the large variety of materials and processes that are used during manufacturing, which often results in complex 

processing lines. Another challenge is how to design electronic systems that can accommodate the differences in drive voltage between different components. 

We will present a roll to roll printable technology platform primarily consisting of electrolyte-based components; electrochromic displays, thin film transistors, diodes, 

sensors, antennas and interconnects. These components have the benefit of being based on a small set of materials, and at the same time the components show 

millisecond switching time at drive voltages around 1 volt. The latter is critical upon integration of thin film transistors with batteries, displays and sensors. We will also 

discuss the need for heterogeneous integration of printed electronics with silicon-based electronics and a strategy for making such integration cost effective.

12:00 pm All Inkjet-Printed Electroactive Polymer Actuators for Active Microoptical and Polytronical Systems 

Mr Oliver Pabst, 

Fraunhofer Institute for Applied Optics and Precision Engineering, Germany 

In this paper we demonstrate all inkjet-printed electroactive polymer (EAP) actuators. A desired application for such actuators is to actively position or deform components 

in microoptical and polymer based electronical (polytronical) systems. The actuators are based on an EAP layer sandwiched between a set of two electrodes on e.g. a 

polycarbonate (PC) substrate. Cantilever-type bending actuators are realized that exhibit a bending deflection caused by piezoelectric strain in the EAP layers when an 

electric field is applied. The electrodes as well as the EAP layer are applied onto the substrate using drop-on-demand inkjet printing. The electrodes are printed using a 

commercially available silver nanoparticle ink (Cabot Corp., CCI-300). In order to sinter the printed electrodes without heating the substrate above its glass transition 

temperature, a low pressure argon plasma exposure was used with a 40 kHz RF generator. This sintering technique enables a selective sintering process of the printed 

features only and is compatible with low TG polymer substrates [Reinhold et al., ?Argon plasma sintering of inkjet printed silver tracks on polymer substrates?, J. Mater. 

Chem., 19, 2009]. The electroactive polymer layers are printed using commercially available solutions of electroactive polymers from Solvay Solexis S.p.A. (solveneTM). 

After printing, the EAP layers are annealed thermally at moderate temperatures. In order to achieve piezoelectric behavior of the actuators the samples are poled in an 

electric field. Actuators with lateral dimensions of 5 x 20 mm and with EAP thicknesses of 10 µm to 15 µm exhibit deflections of approximately 100 µm when a driving 

voltage of 400 V is applied. The resonance frequencies of the as-prepared actuators are between 200 Hz and 300 Hz. These performance data are promising for the 

application in e.g. polymer based microoptical imaging systems, where image quality can be optimized by actively positioning certain components.

12:20 pm Sensors produced by powder-filled pastes 

Ms Claudia Drescher, 

Fraunhofer IFAM, Project Manager, Germany 

Due to the complexity of systems or products, health monitoring of devices is important to gain information about the system?s status and to optimize the maintenance rate. 

Here different kinds of sensors are needed to e.g. detect temperature changes. 

Powder metallurgical sensor coatings offer the advantage of applying a sensor directly onto a device. The functional pastes can be applied to insulated stainless steel, 

powder metallurgical parts and ceramics (e.g. alumina) via screen printing technology. The sensor is functionalized during the following heat treatment in which the 

properties of the sensor can be influenced by the sintering parameters. 

The powder-filled pastes can be produced in high material diversity and allow the use of established printing processes. 

The screen printing technology offers the advantages of a low cost, mass production process. The application of a sensor to a device?s surface leads to new integrated 

functions of a device. A combination of different sensors is possible due to the possibility of a complex screen layout. 

Depending on the quantity to be measured ? i.e. strain, temperature, rotational speed ? different materials are evaluated, e.g. thermocouple standard types (as type T: 

Cu-CuNi) are investigated. 

At the Fraunhofer IFAM a variety of thick-film sensors have been developed which can be applied directly onto parts. Here investigations on the functionality of strain 

gauges or overload sensors, as well as thermocouples have been performed. 

Also the deposition of magnetic sensorial structures is possible, which exhibit either hard or soft magnetic properties. 

The functionality of the different sensors is tested, depending on the sintering conditions, i.e. temperature, dwell time and atmosphere. 

The powder metallurgical produced sensors are checked with adequate testing methods, e.g. a temperature calibration or load tests. 

Metallographic investigations of the sintered layers and interdiffusion zones were performed to study the formation and composition of possible phases.

12:40 pm Inkjet Printed Heaters and Resistive Temperature Detectors for Biological Microfluidic Applications 

Ms Lakshmi Jagannathan, 

UC Berkeley, United States 

Printed electronics is an attractive paradigm for realization of biological microfluidic systems. The large area of typical biological microfluidic systems makes printing 

attractive from a cost perspective. Furthermore, since printing allows for easy integration of disparate materials on the same substrate through spatially-specific deposition, 

printed electronics is particularly attractive for integration of diverse biological microfluidic functionality on the same substrate. While there have been demonstrations of 

printed transistors and biosensors, there have been no demonstrations to date of the critical reactor components required for biological microfluidic applications; in 

particular, virtually all integrated biological reactors require integrated heaters and resistive temperature detectors (RTDs). Resistive heaters, in particular, are used in 

numerous applications such as microfluidics, fiber optics, and electronics/substrate heating. Here, for the first time, we demonstrate inkjet printed resistive heaters and 

resistive temperature detectors specifically designed for biological microfluidic applications. To serve the desired biological application, the heater structures have been 

optimized using COMSOL (finite element method) simulations for uniform and efficient heating. The realized heaters and RTDs are printed using nanoparticle gold ink on a 

biological glass substrate. The inert quality of gold successfully yields heaters and temperature detectors that are nonreactive to solutions used in biological applications. 

Relevant biological processes such as PCR (polymerase chain reaction) and DNA sequencing require temperatures as high as 95?C. The optimized printed heater 

structure herein generates a temperature differential of greater than 100C with an applied voltage of 10-12V. Many biological applications (PCR, Sanger sequencing, 

RT-PCR and other enzymatic reactions, for example) require precise control and stability of temperature, which is also demonstrated in this paper through integration into a 

microchip bioprocessor system capable of PCR.

01:00 pm Screen printed thermoelectric generator in a five layers vertical setup 

Mr Andreas Willfahrt, 

Stuttgart Media University, Research Assistant, Germany 

The development of a screen printed thermoelectric generator (TEG) consisting of five functional layers will be presented. In the governmentally funded research project 

?Printed Thermoelements? screen printing is used instead of the complex conventional production process to assemble TEGs. The major challenge is the need for 

appropriate printing inks comprising of rather exotic functional particles dispersed in binders and solvents to render them printable. Unfortunately, the classic materials like 

bismuth telluride (Bi2Te3) which can be either n- or p-doped is not used here since there are no printing inks available. The deployed materials show a smaller Seebeck 

coefficient than Bi2Te3 but they are optimized for printing. In the author?s opinion the results achieved with the deployed materials can easily be adopted to other material 

combinations including a printing ink consisting of Bi2Te3 particles, which might be developed in the future. 

The thermoelectric generator to be presented comprises of printed silver ink conductors (top and bottom conductors), an insulating mask-layer with cavities permeated by 

two different thermoelectric materials. A self-prepared Nickel ink is used for the n-type leg whereas the p-type leg consists of the conductive polymer Clevios SV3 

(PEDOT/PSS). The cavities formed by the square apertures in the insulating mask will be filled with the p- and n-type thermoelectric materials in subsequent print runs. 

From some tens to hundreds of such thermocouples are connected in series to form a thermoelectric generator. Especially in the layout of the TEG the printing technology 

reveals its superiority. 

The insulating (electrically and thermal) mask-layer must be printed with a high layer thickness (about 100 µm or more) in order to separate the heat source and heat sink to 

maintain the needed temperature gradient. The large layer thickness requires appropriate techniques for preparing the stencils for these printing steps. This will be 

explained in the presentation.

Laser Processing (02:30 pm - 04:00 pm) | LOCATION HARMONIE E / LEVEL C2 

02:30 pm Laser micromachining of organic LEDs 

Mr Tino Petsch, 

3D-Micromac AG, CEO, Germany 

OLED lighting is expected to be one of the fastest growing markets in the area of organic electronics. The state of the art production is mainly based on vacuum deposition 

processes, which, in order to simplify the material handling, will most probably be embedded in a roll-to-roll environment. While reducing the handling costs this also implies 

challenges to the patterning of the several OLED layers. Laser micromachining applying ultra-short pulsed laser sources has the potential to fully satisfy the requirements. 

Within this talk the latest findings on the separate scribing steps P1, P2 and P3 will be presented. 

03:00 pm Maskless ultrafast laser trimming of OTFT devices for low leakage fast switching 

Dr Michael Cooke, 

The Printable Electronics Technology Centre , United Kingdom 

Organic thin-film transistor (OTFT) performance has progressed dramatically in recent years approaching fast the commercial realisation of large-area low cost electronic 

devices on rigid or flexible substrates. A critical issue in high performance OTFT fabrication is the precise direct patterning of the organic semiconducting layer to leave an 

active channel region and the reduction of leakage currents by avoiding conductive paths between devices. This is key for eliminating high resistive and capacitive parasitic 

leakage currents at the insulator/semiconductor interface. To date there are few demonstrated manufacturing processes that can achieve the desired effect of improved 

on/off ratio without having an adverse effect on the channel mobility. Whilst lithography processes can be used, the addition of further masking steps risks making the 

process too lengthy and hence uneconomic at a large scale or in future roll-to-roll processes. This is highly problematic as TFT sizes shrink. Here we discuss an industrial 

laser solution for scalable maskless direct trimming of OTFTs for display or other applications using ultrashort DPSS lasers on especially formulated OTFT materials. 

Experimental measurements including optical profiling, SEM and electrical device characterisation suggest that clean OSC layer removal results in an improved on/off ratio 

with less leakage current whilst producing minimal degredation in mobility. Selective laser patterning could be certainly utilised for athermal, debris-free patterning of 

OTFTs with ultraprecise spatial resolution and depth control.

03:20 pm Laser Ablation of Transparent Conducting Materials for Organic 

Mr Moritz Schaefer, 

Fraunhofer ILT, Germany 

One of the great advantages of polymer electronics is the possibility to produce low cost electronics by fast printing methods. Screen and inkjet printing offer minimal 

features sizes of 10 µm and are therefore not accordable with small structure sizes of a few microns or even sub microns as needed for highly integrated circuits. To 

achieve structures of this size most of the possible methods are very time consuming and thus cannot be applied in a reel-to-reel process. 

Laser processing provides a possible solution for a fast and high resolution patterning method for transparent conducting materials which are needed for OLEDs, organic 

photovoltaics, fully transparent displays and transparent circuits. The ablation of such materials as for example ITO (Indium Tin Oxide) and PEDOT/PSS (Poly (3, 

4-ethylene dioxythiophene) Poly (styrenesulfonate)) is based on photochemical ablation and stress based evaporation. In this paper the ablation at different wavelengths 

from the deep ultraviolet range with excimer lasers up to the infrared range with solid state lasers is discussed. By evaluation of the different thin films using UV/VIS/NIR 

spectrometry measurements the optimal wavelength for micro patterning of each material is determined. The different ablation mechanisms at the different wavelengths are 

examined. 

Special emphasis will be put on the accuracy of the edges of the ablated areas. This has been investigated by different microscopy methods such as optical microscopy, 

white light interferometer microscopy (WIM) and atomic force microscopy (AFM). Different patterning methods, like ablation via mask projection, scanner based ablation 

and ablation via microscopy optics will be compared concerning process speed and achievable highest resolution.

03:40 pm Debris-free maskless selective laser patterning of PEDOT: PSS for organic electronics applications 

Dr Dimitris Karnakis, 

Oxford Lasers Ltd, United Kingdom 

Rapid developments in large-area organic electronics promise thin, lightweight low cost devices for several key applications (OLED, OTFT, OPV, etc) on glass or flexible 

substrates. When directly patterned deposition is not feasible, requiring instead full-area coating and post-patterning techniques, laser processing is gradually emerging as 

a key enabling tool. However, very few reports discuss laser thin-film patterning, especially on flexible substrates. The aim here is to examine the potential of ultrafast 

DPSS lasers for such applications and demonstrate a stable process window for large area selective layer patterning. More specifically, we will present detailed ablation 

studies on the removal of transparent conductive oxides on barrier layers or polyester substrates, metal electrodes on organic layers and conductive polymers 

(PEDOT:PSS) on barrier layers or metal grids. The highly deterministic character of the process will be discussed revealing damage thresholds, indicative process quality 

and process speed limitations. Careful examination with optical profilometry, SEM and high-speed imaging techniques reveals the importance of laser wavelength and 

critically laser pulse duration. A stress-assisted ablation mechanism is believed to be driving this process, which when carefully optised, can result in debris-free, low 

temperature patterning with demonstrably [1] no detrimental effects to the device performance.

04:30 pm CROSSLINKABLE SEMICONDUCTORS FOR USE IN SOLUTION-PROCESSED ORGANIC LIGHT-EMITTING DIODES 

Prof. Klaus Meerholz, 

Universität zu Köln , Germany 

Organic light emitting diodes (OLEDs) based on electroluminescent conjugated polymers are considered as a promising alternative for display and lighting applications, 

mainly due to their better compatibility with low-cost production techniques and large substrates. A challenge is multiple-layer deposition to improve the efficiency of the 

devices and, as a result, their lifetime. 

We have in the past developed photochemically crosslinkable semiconductors for fabrication of complex multilayer OLED [1] and lithographic RGB-pixelation down to the 

micron scale. [2,3] Grey-scale lithographic capability has been demonstrated, allowing the fabrication of multiple cavities with different lengths in a single processing step 

and thus permits monolithic integration of multiple OLEDs with different emission wavelengths on a single substrate.[4] By use of nanoporous hole-injection layers improved 

outcoupling has been demonstrated.[5] Recently, we demonstrated a surface-initiated crosslinking process with high potentials in printing and 3D-coatings.[6] After curing 

the materials feature excellent thermal robustness, allowing to process on top even elevated temperatures (e..g. up to 200C).

05:00 pm Development and Large-scale Manufacturing of Fullerenic Materials for Organic Electronics Applications 

Dr Henning Richter, 

Nano-C, Inc., United States 

Fullerene-derivatives such as Phenyl-C61-butyric acid methyl ester (PCBM) are electron-acceptor materials which, in conjunction with suitable electron donors, are highly 

critical building blocks of organic photovoltaic devices (OPV) and photodetectors. Successful commercialization of such devices requires large-scale supply of, high-quality 

fullerene derivatives. While current device performance may be sufficient for first commercial products, a new generation of fullerene derivatives is expected to be 

necessary to enable the full market potential. 

Initially developed in the Department of Chemical Engineering at the Massachusetts Institute of Technology (MIT), combustion synthesis of fullerenes has matured at 

Nano-C into a robust industrial process of demonstrated scalability. Controlling well-defined operating parameters, premixed combustion allows for the selective formation 

of either fullerenes (C60, C70, C84, etc.) or single-walled carbon nanotubes (SWCNT). Large-scale manufacturing of C60 and C70 fullerenes including their purification will 

be described. Procedures and infrastructure, established at Nano-C, for meeting current and future market needs of fullerene derivatives will be presented. Synthesis, 

chromatographic separation, and detailed quality control by means of several complementary analytical methods will be addressed. Ongoing development efforts of 

fullerene functionalization schemes, assisted by quantum chemical calculations, targeting optimized electronic structure that leads to high-voltage OPV devices will be 

discussed. Strategies allowing for improved active layer morphology, necessary for enhanced charge transport and best performance, will be described. 

Manufacture of SWCNT, including control and assessment of their characteristics such as length using a range of spectroscopic and electron microscopy techniques will be 

presented briefly. Formulation of SWCNT in inks suitable for their use as transparent conducting electrodes and other organic electronics applications will be outlined.

05:20 pm Flexible Transparent Conductor Based on Graphene-PEDOT/PSS Thin Film Prepared by One-step Electrolytic Exfoliation 



Graphene is a potential candidate for flexible transparent conductor (TC) due to its excellent electrical conductivity and optical transparency. Nevertheless, the development 

of graphene based TC has been hindered by the lack of efficient and low cost methods for the synthesis and large-scale high-quality thin film production. Recently reported 

CVD growth on flexible copper substrates and roll-to-roll transfer process for large area graphene synthesis is considered expensive and impractical due to multi-substrate 

and high temperature processing. Organic solution-based route based on chemically-reduced graphene dispersion is more attractive owing to its low cost, low temperature 

processing and ease of large-scale production. However, it suffers from poor processablity because of multiple chemical processing steps. In this work, an innovative 

transparent graphene-PEDOT/PSS conductive ink is developed by a simple one-step electrolytic exfoliation process instead of direct dispersion of graphene nanoflake into 

PEDOT/PSS in post-processing step. The characteristics of graphene-PEDOT/PSS materials are systematically studied by varying electrolytic voltage and time. To study 

optical and electrical properties, graphene-PEDOT/PSS thin film was spin coated on a glass substrate at 1000 rpm and baked at 100 ?C for 1 hour. From SEM 

characterization, high-quality single crystal tetragonal graphene structures in PEDOT/PSS film is obtained at an optimum electrolytic voltage of 8 V. The transmittance is 

found to decreases by around 3% while electrical conductivity increases by more than a factor of three as the voltage increases from 3 to 8 V but then becomes much less 

voltage dependent when the voltage further increases. Moreover, graphene-PEDOT/PSS films synthesized at the highest voltage of 12 V and the longest time of 40 h has 

shown the highest figure-of-merit of 4.77, which is more than twice higher than that of PEDOT/PSS film. The results suggest that graphene-PEDOT/PSS material prepared 

by the proposed one-step synthesis is promising for transparent conductor applications.

05:40 pm Polythiophene: polyethylene blend semiconducting thin-films and transistors by wire-bar coating 

Dr Craig Murphy, 

National Physical Laboratory, United Kingdom 

Organic semiconductors provide the potential for low cost integrated electronic circuits on flexible plastic substrates. In order to enhance the capability for formability and 

flexibility of plastic transistors, blended material systems incorporating mechanically tough polymers, such as polyethylene, have recently been created. These mixed 

materials possess a higher degree of complexity than single polymer semiconductors and require proper investigation of their physical and chemical structure, plus 

electrical properties. Here, we develop the first examples of wire-bar coated thin-films and transistor devices incorporating polythiophene : polyethylene blend organic 

semiconductor systems, examining the physical nanostructure, surface chemical composition and electrical characteristics, as a function of polythiophene : polyethylene 

component ratio. Wire-bar coating is a simple deposition method for preparing large areas of thin organic films at low cost and processes developed on such equipment are 

amenable to scale-up via techniques such as slot die coating, including in roll-to-roll fabrication systems. 

The morphology of the semiconductor layers produced has been examined by atomic force microscopy, transmission electron microscopy and X-ray photoelectron 

spectroscopy methods to reveal a strong structural dependence on initial composition, with clear evidence of phase separation, including vertical segregation. The 50 : 50 

blend (by weight) exhibits a particular striking morphology, whereby micellar regions of semi-crystalline polythiophene (100s nm diameter) are enclosed by a matrix of 

lamellar polyethylene material (25-50nm lamella width). In terms of thin-film uniformity all the samples examined were homogeneous over large areas and the morphologies 

were reproducible between substrates processed in different coating runs. Bottom gate-bottom contact transistor devices were fabricated using such blends as the 

semiconductor layer and the field-effect charge carrier mobility was characterized as a function of blend composition. The combination of polymer blend semiconductors 

and large area deposition methods, such as wire-bar coating, provides a route to low cost, high performance, flexible plastic electronic circuits and systems.

spite of this, actual vehicles exhibit compact dimension, maintaining low emissions and reduced consumptions. The evolutionary approach, aiming at the use of new

- The availability of the state-of-the-art nanomaterials and micro-nano technologies is essential, but in this brief overview we emphasise that, when dealing with a complex

at the vehicle as a whole.

11:30 am Conductive Ink-Jet Printing of Silver and Air-Stable Copper inks for Flexible and Plastic Electronics 

Mr Michael Grouchko, 

The Hebrew University of Jerusalem, Israel 

One of the greatest challenges in fabrication of flexible and plastic electronics devices by printing is to obtain highly conductive patterns at sufficiently low temperatures 

which will not damage the heat sensitive substrates. Another challenge is to achieve it by the use of low cost metallic inks. However, to date, sufficient conductivity of 

metallic patterns was achieved usually after prolonged heating at elevated temperatures by the use of highly cost metals (silver and gold), thus limiting fabrication of low 

cost plastic devices. 

We report new copper based metallic inks which anable to achieve high conductivities of printed patterns. These copper inks contain copper nanoparticles synthesized in 

aqueous medium, tailored to be sintered at low temperatures. One of the major challenges while using copper is to prevent its oxidation while exposed to air, which in our 

case is prevented by coating the copper core nanoparticles by a thin silver shell. 

These approaches allow the formation of low cost conductive patterns on flexible and plastic substrates is enabled, for example, the printing of electroluminescence devices 

on PET substrate. 

12:00 pm Low temperature processing of inkjet printed metal oxides and nanoparticles 

Dr Nenad Marjanovic, 

Fraunhofer Institute for Electronic Nano Systems ENAS, Senior Scientist, Germany 

Amorphous metal oxides and nanoparticles have numerous advantages due to their atmospheric and temperature stability, as well as relatively high field-effect mobility, 

which make them competitive candidates to be integrated into functional devices and electronic systems. However, high sintering temperatures, in some cases up to 400 

°C, are required to remove residual organic components upon printing, as well as to sinter the printed film to impart continuity. The organic additives are necessary to 

prepare stable solutions or dispersions of these materials as inkjet inks. Therefore, material design, inks formulation, printing and low temperature film formation/processing 

are of highest importance, in order to enable the deployment of those materials in electronic systems on polymer substrates (e.g. Polyethylene terephthalate (PET)), which 

are commonly used for Printed Electronics. Here, we are reporting on the characterization and application of inkjet printed amorphous Silicon oxide layer on PET. The 

sol-gel process was applied for obtaining Silicon oxide ink. The inkjet printing, sintering behavior under room temperature, and the effect of solvent and surfactant on silicon 

matrix were investigated. The studies on film formation, morphological and electrical film characterization will be presented. In addition, colloidal Ferromagnetic 

nanoparticles synthesized in organic solvents were also inkjet printed. The influence of capping agent such as oleylamine and oleic acid on ferromagnetic nanoparticles 

was investigated. Results on room temperature film formation will be presented.

12:20 pm Effect of nanoparticle distribution and ink composition on the electrical resistivity of laser annealed inkjet printed silver interconnects in a real-time experiment 

Dr Alessandro Chiolerio, 

Politecnico di Torino, Italy 

We report a study on the effects induced by nanoparticle (NP) diametre distribution and solvent 

choice on the electrical resistivity of silver lines realized by means of inkjet printing on a flexible 

kapton substrate. In a previous work a laser annealing process to promote sinterization was 

exploited to reach the best results in terms of conductivity and was compared to a more traditional 

hotplate annealing [1]. The Ag ink we used is basically an aqueous colloidal dispersion of silver 

nanoparticles (NP) [2]; a specific synthesis procedure allowed us to control the diametre 

distribution. Metal NP are dispersed in a mixed solvent of propylene/ethylene glycol, water and 

ethanol; the solid loading of the ink is 21-24 wt %. The ink-jet printed silver lines were realized 

using a piezoelectric Jetlab® 4 printer from MicroFab Technologies Inc. A thermal treatment was 

performed in order to promote NP coalescence, allowing complete solvent removal and electrical 

percolation. Both the classical hotplate and a Diode Pumped Solid State (DPSS) laser beam within a 

specific range of power / speed conditions were experimented, using a specific test fixture allowing 

the acquisition of real-time resistance profiles during either the laser annealing or the hot-plate one. 

The laser used to anneal the sample was a DPPS laser system made by Microla Optoelectronics 

(MLQ-20 series). This DPSS laser system has an end-pump configuration and an output wavelength 

of 1064 nm linearly polarized with a maximum power density of 1300 W/cm2 in continuous wave 

mode. The effects of geometry, NP distribution and solvent were clarified.

12:40 pm Transparent nanocomposites with high dielectric constant 

Mr Tobias Lehnert, 

INM ? Leibniz-Institut für Neue Materialien gGmbH, Germany 

In general low temperature processable materials with high dielectric constant are required for applications on flexible organic substrates, for example in printed electronics. 

Organic polymers which can naturally be used in printed electronics suffer from low dielectric constants, whereas ceramic capacitors are well established in conventional 

electronics but they need a high temperature sintering step to develop their superior dielectric properties. To combine these exclusive properties mainly low temperature 

processable polymers with embedded functional ceramic particles are investigated in the literature. The 0-3 connectivity composite approach usually fails for applications 

were transparency is a second requirement next to the low temperature processability, for example in display applications. By varying the filler content in the composite we 

were able to develop films with high dielectric constants in the range of ?r ? 40 which exceeds available polymer solutions by concurrently maintaining the high 

transparency of the polymer matrix in the visible range. The curing temperature of these films is below 200°C which makes them appropriate for printed electronics. This 

promising result was obtained by using small BaTiO3 nanoparticles as ceramic filler and providing a very good dispersion state of the particles in the polymer matrix as a 

maximum agglomerate size of ~ 20 nm is required for transparency. Besides its good dielectric properties these multifunctional composites exhibit a very high refractive 

index which opens possible application fields in printed optics or printed optoelectronics.

01:00 pm Electrical Properties of SAM Modified ITO Surface using Aromatic Small Molecules with Double Bond Carboxylic Acid Groups for OLED Applications 

Mr Ali Kemal Havare, 

Ege University, PhD student, Turkey 

The energy level alignment and charge injection in organic light emitting diodes (OLED) device is a significant step to elucidate this organic semiconductors and to optimize 

their performance. The weak bonding at the organic/inorganic interface in OLEDs due to incompatible structural difference is one of the limiting parameters for the stability 

and performance of OLEDs. One of the most important issues in OLED devices is to be able to control electrode/organic interface and the differences between the work 

function of the anode (ITO) and HOMO level of the organic semiconducting hole transport layer (HTL) material. This difference can cause high turn on voltage, low 

efficiency and restricts hole-injection [1-2]. 

In this work, 5-[(3-Metifenil)(fenil)amino]izoftalic acid (5-MePIFA) and 5-(Difenil)amino]izoftalic acid (5-DPIFA) organic molecules were synthesized to form self-assembled 

monolayer on indium tin oxide (ITO) anode to enhance hole transport from ITO to organic hole transport layers such as TPD and NPB. SAM molecules with 1mM were 

prepared at room temperature in ethanol solution. ITO substrates were kept in ethanol-SAM solution for 48 hours to be covered with SAM monolayer. The modified surface 

was characterized by atomic force microscopy (AFM) and Scanning Tunneling Microscopy (STM). The change in the surface potential was measured by Kelvin probe force 

microscopy (KPFM). Our Kelvin Probe Force Microscopy (KPFM) measurements showed that the surface potentials increased more than 100 mV with reference to bare 

indium tin-oxide. The Schottky barrier parameters have been obtained from I-V measurements. The results show that the threshold voltage on OLEDs with modified ITO is 

lowered significantly compare to OLEDs with unmodified ITO.

Systems and Implementation Issues (02:30 pm - 04:00 pm) | LOCATION HARMONIE D / LEVEL C2 

02:30 pm Solar Energy Harvesting Integration in Mobile Devices 

Ms Stephanie Fajtl, 

ST Ericsson, Designer, France 

SOLAR ENERGY HARVESTING INTEGRATION IN MOBILE DEVICES 

Mobile, computer and consumer industry are converging somehow to bring a real new user experience by opening the door of a wonderful connected world. The mobile 

industry is facing one of it biggest challenge : users are expecting faster processors, bigger screens, high resolution camera, playing game, be always connected whatever 

their location, broadcasting TV or movies, listening high quality music and with no need to charge the mobile phone every time. 

Despite real progress to make more efficient and low power devices and advance in battery technologies, the gap between the user expectation and the energy available is 

unlikely growing year over year. 

To face to this main challenge we propose to harvest energy from any sources and most important to contribute to reduce use of carbon energy and reinforce recycling. 

Technologies to gather energy present interesting performances and announce big improvements to generate enough power for the application. The way to manage the 

available energy and distribute into the system is fundamental. 

Solar energy present great interests: free, available relatively everywhere and best in class in term of efficiency. 

ST-Ericsson?s aim is to put in place energy harvesting for mobile devices which reduces battery drain to zero in standby mode which will be a great achievement but 

another one equally important is to extend battery lifetime. 

Today we demonstrate that thanks to a photovoltaic cell of just 5x5cm an MP3 playback is running using only solar energy. 

Printed, Organic or not, Photovoltaic technologies present great advantage in term of integration in mobile devices which is a major point to be massively adopt in mobile 

devices. 

I will propose to present solar energy harvesting in mobile devices study in three main points: 

?Integration constraints link to mobile devices 

?How much power can we expect for different technologies addressing different use cases and different mobile devices 

?How to manage the harvested energy.

03:00 pm Recyclability Aspects of Smart Labels Placed on Liquid Packaging Board 

Mr Klaus Villforth, 

TU Darmstadt, PMV, Senior scientist, Germany 

The contribution of PMV is focused on the recyclability of printed organic electronics concerning the paper chain. This topic comprises the behaviour of labels in the 

repulping process, the separation/deposition of label fragments and peeled off components, as well as the identification of harmful substances. 

A new method developed by PMV assesses the recyclability of packaging products. In recent trials, plastic labels with printed organic electronic have been placed on liquid 

packaging board with different adhesives. Some adhesives particularly dispersion adhesive release labels due to the rough process conditions of repulping. In this case, 

parts of the printed electronics are exposed to the harsh environment. Layers will detach from the label and may contaminate fibre suspension with detrimental substances. 

Trials with hot melt adhesive demonstrate that it is possible to retain the label on the coated surface of liquid packaging board without affecting disintegration of the fibre 

layer. Thus, smart labels can be efficiently protected against mechanical and chemical impacts. This implies a sufficient bonding of the functional layers. Peel test helps to 

find appropriate combinations. 

The presentation will show test methods, results of trials in laboratory scale and measures necessary to ensure sustainability in terms of the European Declaration on 

Paper Recycling. 

Objective of the current research project Polytos is to develop printed organic circuits with integrated sensors capable of recording data such as temperature, humidity or 

light exposure. These types of printed organic circuits could be used as printed smart labels in the future. 

A smart label for milk in beverage carton shall predict the use by date based on the actual storage temperature. This first basic demonstrator will be a plastic label with 

printed organic electronics placed on liquid packaging board.

03:20 pm Charge Pump Circuit Using Printed Organic Diodes and Capacitors 

Mr Petri Heljo, 

Tampere University of Technology, Research Scientist, Finland 

The development of organic electronic components and circuits offers the possibility to manufacture flexible and lightweight electronics using cost-effective processes. 

However, useful circuits require printing of more than one kind of device using compatible processes. Previously, we have demonstrated diodes with high rectification 

ratios, low reverse currents and small threshold voltages that work as rectifiers at MHz frequencies fabricated using only air-stable materials and processes that are 

scalable to high volume production [1]. Here we report gravure printed organic diodes and capacitors and their application in an organic voltage multiplier circuit. 

In 13.56 MHz RFID applications the voltage supplied by the antenna is limited, which creates a need to generate DC voltages higher than the AC signal amplitude in order 

to power circuitry. Printed 13.56 MHz voltage multipliers have been demonstrated using oxygen sensitive aluminium cathode inks and a semiconductor employing inorganic 

ZnO nanowires [2]. Organic voltage multipliers have been demonstrated at kHz frequencies [3]. However, the output voltage of the circuit was limited due to high threshold 

voltage and low rectification ratio of the diodes. Here, we demonstrate a voltage multiplier based on printed, air stable organic diodes. Furthermore, we demonstrate printed 

capacitors with a capacitance of 2 nF/cm2. A simple voltage doubler circuit delivers a DC output voltage of 1.5 times the output voltage of a half-wave rectifier, which 

exceeds the AC input signal amplitude.

03:40 pm Binary clock with interactive function on flexible paper substrate 

Dr Thomas Knieling, 

Fraunhofer ISIT, Scientist, Germany 

In this paper we present a binary clock demonstrator on flexible paper substrate whose conductive lines where printed in a low invest inkjet printing process (Fig. 1 left). 

The low voltage (5V DC) driven clock is adjustable by simply touching printed electrodes on the carrier surface. The binary encoded time is shown by a LED display. 

For printing a common EPSON Inkjet printer C88+ was used. The used ink consists of silver particles with average diameters of about 55 nm disperged in an ethylene 

glykol based solution. The silver lines where printed at room temperature on photo paper substrates and afterwards cured at 100 °C for 2 h, where solvent residues were 

brought out and silver particles were sintered. The obtained conductivity was then 2,9 ± 0,2 Sm/mm². For fixing common SMD electronic parts a conductive epoxy adhesive 

containing silver particles was used and cured at 80 °C for 3 h after deposition. Thus the whole production process is limited to low temperatures suited for cheap subtrate 

materials like paper, PET or PEN. 

The printed lines withstand about 64000 bending cycles with bending radii of 1 cm. Afterwards small cracks with resistances increased from 100 Ohm to about 20 MOhm 

are observed (Fig. 1 right). Glue connections between components and silver surfaces should be covered by protection layers. 

Since only office printing equipment is used the invest is at least two magnitudes lower than for industrial print head systems. However, printing resolution is limitied to 

about 0,2 mm. This is sufficient for fast evaluation of simple systems but will hardly be usable for printing highly integrated circuits or electronics parts like resistors or 

capacitors where exact geometric features are demanded. Thus main advantages of this technique lie in its low price, simple installation and in its layout flexibility. Low 

invest rapid prototyping of low or medium standard electronic devices will be the main application area of this process.

Novel Inks and Processes (04:30 pm - 06:00 pm) | LOCATION HARMONIE D / LEVEL C2 

04:30 pm Design of semiconducting materials and polymer dielectrics for printed transistor applications 

Dr Silvia Janietz, 

FhG-IAP, Germany 

OFETs based on solution-processible polymers as well as small organic molecules have obtained impressive improvements in performance in the last years. But the aim is 

to realize integrated circuits based only on organic components to reach the potential for low cost processing. A critical point in the OFET is the complete system organic 

semiconductor/ organic dielectric. On the one side the interface between the organic dielectric and the organic semiconductor could be influenced through modification of 

the chemical structure of the applied semiconductor polymer. Therefore a novel poly(3-[hexyl-co-3,6-dioxaheptyl]-thiophene) was synthesized. The dioxaheptyl-groups in 

the side chain of the polymer backbone result in good wetting behavior of the PMMA-solution on top of the P3HT-doh layer which we do not observe when we use 

P3HT-layers. The measured performance on flexible OFETs regarding mobility seems comparable as well. The copolymer was formulated for inkjet printing processes and 

we determine a comparable behavior characteristic of the OTFT to devices that based on spin-coated semiconductor layers. On the other side new adapted organic 

dielectrics are developed to adjust the interface to the organic semiconductor. For this reason new thermally crosslinkable dielectrics are synthesized which have the 

opportunity to integrate different kind of monomer units to adapt the organic semiconductor. At first inert polymers were prepared with two different crosslinkable units. 

These polymers have the possibility to be crosslinkable in a thin layer through a following thermal or UV-initiated step. The polymers were synthesized through a radical 

solution polymerisation. The copolymers consist of phenol- and phenoxymethyloxiran-units in different ratios in the polymer backbone. This synthetic strategy offers the 

possibility to realize very thin dielectric layers to reduce the operation voltage of OFETs to some volts. The electrical stability of thin layers using this dielectric as well as the 

functionality in OFETs were proven.

05:00 pm Plasma Functionalized Carbon Nanotubes for use in Functional Inks 

Mr Neil Graddage, 

Swansea University, PhD Student, United Kingdom 

The rapid development of printed electronics provides a continuous demand for novel materials and functionalities for inks. One material which has been the subject of 

much research interest in recent years is carbon nanotubes (CNTs). The dispersion of CNTs is not trivial due to particle aggregation. One method for improving the 

solubility of CNTs is to bond molecules to the surface of the material, a process known as functionalisation. Selection of appropriate molecules decreases nanotube 

agglomeration and allows improved bonding with the resin and dispersants. This is normally achived by acid processing, however this is known to adversely affect the 

electrical and mechanical properties. 

In this work a proprietary plasma processing technique (Haydale Ltd.) has been investigated. Functionalisation is achived by introducing defects to the surface of the CNTs 

to facilitate bonding without causing the severe structural damage typically seen after conventional acid processing. Carboxyl, Hydroxyl or amine group molecules are then 

bonded to the defects via atmospheric exposure. 

Suitable base inks were developed using functionalised and non functionalised CNTs. A full factorial experiment was performed varying the agitation energy, CNT 

concentration and the type of functionality applied. Fluid properties of the inks were characterised by studying the rheology and surface tension. The inks were coated onto 

a PET substrate. The conductivity and transmission properties of the printed layer were studied and average agglomerate size was investigated. 

The deagglomeration as a result of the plasma functionalisation provided a 60% improvement in sample homogeneity with a 43% reduction in agglomerate size compared 

to non-functionalized samples. Despite the introduction of defects to the nanotubes there was still a 7% improvement in the sheet resistivity. 

The use of plasma processing as a method for the functionalisation of CNTs for use in conductive inks allows for reduced processing time and improved electrical 

performance.

05:20 pm Quantum dots for hybrid inorganic-organic LED devices: Materials, processes and applications 

Dr Armin Wedel, 

Fraunhofer Institute for Applied Polymer Research, Germany 

The most promising inorganic luminescent nanoparticles are the quantum dots (QDs) based on core-shell semiconductor materials due to their tunable and highly efficient 

emission properties as well as their thermal and photochemical stability. Despite the wide research on the synthesis of cadmium selenide/zinc sulfide (CdSe/ZnS) only few 

approaches have been attended to achieve fast and large-scale fabrications for industrial applications. The use of QDs as light-emitting materials in OLED (organic 

light-emitting diodes) technologies requires highly purified and surface-modified nanomaterials. For the CdSe system, published syntheses procedures were adapted and 

optimized in regard to parameters like the type of precursors and stabilizers, their concentration and ratio, the reaction conditions as well as regarding the shell formation. A 

facile and fast purification procedure was developed to prepare the QDs for spin-coating techniques. QDs with high quantum yields (>50%) and narrow emission (FWHM < 

30 nm) could be fabricated on a multi-gram scale. OLED devices were assembled successfully by spin-coating these QDs to thin films. The main scope of current research 

on QDs is the substitution of the inherent toxic cadmium based QDs by more environmentally friendly materials like indium phosphide (InP). First approaches show the 

potential of this system although optimal synthesis conditions are less known in literature. In order to receive high-quality materials suitable for OLED devices the synthesis 

of InP QDs with narrow band emission as well as high quantum efficiencies are currently under investigation. On the basis of the optimized InP/ZnS synthesis and adapted 

surface modification we could fabricate the first hybrid organic inorganic LED device based on non-toxic InP QDs. The multi-layer OLED device could be even assembled 

on rigid glass substrates or flexible polymer substrates.

05:40 pm Electrical sintering of printed metal structures for mechanical sensors 

Mr Christian Werner, 

Fraunhofer IFAM, Germany 

Today, physico-mechanical sensors like strain gauges, thermo-elements or resistance thermosensors are often discrete devices that have to be mounted onto the surface 

of the part (SMD). With the evolving possibilities of printed electronics it is desired not only to print conductive patterns but additionally sensors or sensor arrays. Maskless 

printing techniques, like Ink Jet and Aerosol Jet®, are able to print microstructured metal patterns from nanoparticulate inks on virtually any substrate. The thermal 

treatment of the printed structure is often done by furnace, with temperatures usually above 150 °C. Furnace sintering results not only in a high thermal load of the whole 

part or substrate, but also limits the general substrate selection. Another issue for sintering printed structures is the differing of electrical resistivities due to variations in 

process reliability of maskless printing processes for specific printed patterns, like strain gauges. 

The electrical sintering process is an unconventional, but promising candidate for sintering printed metal patterns to a specific target resistivity, as well as reducing the 

thermal load on the substrate. This work is focusing on the characterization of electrically sintered printed metal structures in comparison to the thermal processing of these 

structures by furnace. For this purpose, commercially available conductive inks, like gold or silver as well as resistive inks under development, like copper-nickel, are 

printed by Ink Jet or Aerosol Jet® on various substrates. 

With electrical sintering, it was possible to achieve highly conductive metal structures within some seconds of treatment. Besides electrical characterization, scanning 

electron microscopy with focused ion beam is used to analyze surface morphologies and cross-sectional areas of the different metals after electric and conventional 

sintering. Further on, dynamic testing of printed strain gauges is performed to give information about the mechanical load capacity.

device, an efficiency of 37 lm/W is reached. A similar approach using a vacuum processable scattering material in top emission OLED architectures on metal substrate

commercialisation of large area OLED lighting are addressed. Within this project 

Fraunhofer IPMS performs R&D on up-scaling topics aiming at tiling of large-area 

lighting consisting of seamless panels of 33x33 cm². 

Starting from the design rules given by the screen printing processes for substrate 

patterning developed at COMEDD we will present the design, optimisation and 

realisation of 33x33cm² OLED-panels with respect to OLED-stack and homogeneity 

requirements. The panels are based on the on-substrate tiling concept with 5 segments 

connected in series. Furthermore it uses busbar structures, a metallization layer that 

helps spreading the current evenly over the substrate to ensure homogenous light 

emission. The total active area is 828 cm2 on a 33×33 cm2 substrate yielding an aperture 

ratio of 76%. This is a major step towards square-meter-wide lighting walls or ceilings, 

one of the main goals of OLED100.eu. 

The discussion of electro-optical key parameters and fabrication yield of the panels 

including the demonstration of such 33x33cm² panels will be the main topic of the talk.

Plextronics Inc., Director, Inks Business, United States 

Organic Photovoltaics (OPV) can be a viable source of low cost renewable energy for on-grid deployment, provided challenges related to device efficiency and lifetime can

Plextronics, Inc., a world leader in printed electronics, is developing solution processable inks and technology to address this growing market demand. This includes a four 

pronged approach towards developing flexible OPVs: (1) materials development to design and synthesize p-type polymers and n-type semiconductors that can be blended 

to yield high performance OPV cells; (2) ink development to formulate the materials into inks that can be coated on to large-area substrates using commercial coating 

techniques; (3) device engineering to optimize the device design, architecture for high performance and stability at the module level; and (4) device manufacturing

12:40 pm Progress towards realization of all solution processed ITO free OPV 

Dr Jan Kroon, 

ECN , Project manager/scientist, Netherlands 

The growing interest in organic photovoltaics (OPV) is caused by their promise 

for low cost energy conversion. In order to have an impact on the power generation 

market on the longer term, OPV should combine high power conversion efficiency with 

low production costs, high speed production, short energy payback time (EPT), contain 

only abundant materials and yield long term device stability. In order to address these 

requirements, we have developed and proved a set of device structures. 

To replace ITO, a device concept is developed based on highly conductive and 

solution processed PEDOT in combination with printed silver grids. Apart from the cost 

saving aspects by replacing sputtered and post-patterned ITO it is demonstrated by 

modeling that the individual cell dimensions can be substantially larger without 

decreasing actually the cell performance. 

Another device concept has been developed in which polymer solar cells are built 

on metal foils. These devices dwell on the well known ?inverted? polymer solar cell 

device structure with proven advantages in terms of device lifetime. Since a metal foil is 

applied as substrate, an excellent combination of flexibitity and barrier properties is 

inherent to this device concept. 

By combining elements of the above described cells, a novel polymer solar cell 

structure is manufactured in which all layers, including electrodes, are solution processed. 

This roll-to-roll compatible device yields an efficiency of 2.5 % (P3HT:PCBM as active 

layer).

01:00 pm Parameter extraction by simulation-based characterization of organic solar cells 

Prof. Dr Beat Ruhstaller, 

Fluxim AG, Switzerland 

Organic electronics is a rapidly growing industry in which materials synthesis, materials characterization and device optimization plays a crucial role in the quest to achieve 

ever better device performance and lifetime. The challenges are manifold. Apart from material synthesis, fabrication of record lab-scale devices and high-volume 

production, there is a strong need for quick and reliable material parameter determination and device optimization. We address these challenges by presenting a 

comprehensive simulation software for organic solar cells and OLEDs that seamlessly describes the photon, exciton and electron processes. In this talk we focus on the 

characterization of solar cells with dedicated experiments and numerically simulate common characterization techniques such as charge extraction transients by linearly 

increasing voltage (CELIV), steady-state current-voltage curves and spectral photocurrent response with a fully-coupled opto-electronic model that calculates light 

penetration, photocarrier generation as well as charge extraction [Häusermann et al., J. Appl. Phys.; 106, 10450 (2009), Neukom et al., Proc. SPIE 7722 30, (2010)]. 

The transient and steady-state model also considers the series resistance of the setup. For a couple of bulk heterojunction solar cells we use this model to fit several 

experimental datasets as a function of light intensity and temperature simultaneously. Thus we can estimate basic material parameters like the charge carrier mobility, 

recombination coefficient, internal quantum efficiency and injection barriers. The mathematical quality of the fits is assessed by a covariance analysis and the determination 

of confidence intervals for the fitted parameters.

Sintering of Inorganic Materials (02:30 pm - 04:00 pm) | LOCATION HARMONIE E / LEVEL C2 

02:30 pm Reducing Screen-Printed Copper Oxide to Copper on Paper Substrates at Industrial Speeds in Air 

Mr Stan Farnsworth, 

NovaCentrix, VP Marketing, United States 

Printed electronics developers have long sought low-cost high-conductivity ink products, and often target copper as a candidate ink material. Copper inks in actuality 

present challenges due to oxidation, and overcoming the oxidation either at low cost and/or on low-temperature substrates such as plastic films and paper had proven 

elusive. Recently however NovaCentrix has presented the Metalon ICI-001 and ICI-003 copper-oxide inkjet inks in conjunction with the PulseForge® tools. The inks utilize 

novel reduction chemistry activated by the PulseForge tools to convert the low-cost CuO ink material into Cu thin-film in-situ on the printed substrate. NovaCentrix is now 

presenting that technology applied to produce a screen-print ink product. Metalon ICI-020 is a screen-print ink based on the CuO reduction chemistry, and when processed 

with a PulseForge tool yields a highly-conductive copper film on ordinary 110 lb paper card stock. Because the starting material is inexpensive copper oxide instead of 

copper, and the conversion process takes only about a millisecond, the cost of such a film is much cheaper than current metallization technologies enabling low cost, 

high-volume printed electronics. The traces presented were printed with a 325 mesh screen and are 2 ? thick based upon coat weight, resulting in a bulk resistivity of about 

10X that of pure copper. Similar performance levels were obtained on a variety of cellulose substrates including standard cardboard boxes and ordinary photocopy paper. 

Typical curing times were about 0.2 sec at speeds of 40 fpm on a conveyor in ambient air.

03:00 pm Conductivity and Adhesion Study of Plasma-sintered Nanoparticle Silver Ink 

Mr Juha Niittynen, 

Tampere University of Technology, Researcher, Finland 

Electronics manufacturing industry is looking for a supplement for the traditional manufacturing technology to meet the new demands of the electronics markets. In recent 

years inkjet-printing has been considered as one of the most promising alternatives. The main advantage of inkjet-printing over conventional production technologies is that 

it is a completely additive and digitally controlled manufacturing process. Additive processing enables material savings, whereas a digital process control enables easy 

product customization and rapid prototyping. However, inkjet-printing has some challenges that need to be resolved before the technology is ready for a large-scale 

manufacturing. One of the most serious challenges is the high production cost of inkjet-printing compared to other manufacturing technologies. Amongst the factors causing 

high production costs are expensive high-temperature plastic substrates, which are currently needed because of the high sintering temperature of nanoparticle inks. 

Low-temperature sintering techniques may lower production costs as they enable the use of cheaper low-temperature plastic substrates. 

Plasma sintering is one of the alternatives for low-temperature sintering and it has been used to sinter nanoparticle inks without damaging the thermal-sensitive substrate 

material. Test structures were inkjet-printed using a silver nanoparticle ink (Harima) and sintered using a low pressure plasma exposure in order to evaluate the feasibility of 

plasma-sintering in the electronics manufacturing. Conductivity and adhesion tests were conducted and were compared to thermally-sintered reference samples. 

The study showed that adequate conductivity can be achieved with plasma-sintering. However, the adhesion is inferior to thermally-sintered samples. In this case low 

adhesion means that the conductive structures are more susceptible for mechanical damage and, therefore, have a lower reliability, which is an essential factor for today?s 

electronics. Therefore, the mechanisms to improve adhesion of plasma-sintering, for example by a surface treatment prior printing, must be investigated in future in order to 

use it in large-scale electronics manufacturing.

03:20 pm Inkjet printing and microwave flash sintering of conductive nanoparticles for R2R applications 

Dr Jolke Perelaer, 

Friedrich-Schiller-University Jena, Postdoc / project manager, Germany 

In recent years, inkjet printing is increasingly used as a flexible and digital patterning technique in the field of microelectronics. The main advantages of inkjet printing are its 

ease of processing and its potential for mass production. Furthermore, based on its digital properties, inkjet printing is both a flexible and low cost technique, since materials 

are used in an efficient manner, compared to other patterning techniques, like non-digital printing techniques and spin coating, which significantly reduces waste production. 

During the last years, there has been a growing interest in printing silver inks as a basis for conductive tracks in microelectronics applications, including OLED, OPV and 

RFID. 

Currently, much interest is dedicated to inkjet printing of conductive materials, such as silver nanoparticles; as an effect of their reduced particle size, the melting 

temperature is reduced significantly. Although the sintering temperatures are reduced to well below 300 °C, these temperatures are not compatible with polymer foils, which 

are required for applications in plastic electronics. 

We have used alternative techniques to sinter inkjet printed silver nanoparticles that are compatible with common polymer foils, such as PET and polycarbonate. The 

process involves either a low pressure argon plasma exposure or microwave radiation. 

Recently, we made good progress with combining the two alternative techniques, which enhances the process of creating conductive patterns on polymer substrates in two 

ways: firstly, the features' conductivity can be increased by using a hybrid sintering setup and, secondly, the overall sintering time can be reduced by using the so-called 

flash sintering approach. Hereby, sintering times can be reduced from more than one hour to a few minutes or even seconds. Furthermore, the obtained conductivity is 

between 10 and 50% of bulk silver, while leaving the polymer substrate unaffected. 

These conductive features may be used in many plastic electronic applications.

03:40 pm Cost Effective Patterning of Conductors Utilizing Silver Nanoparticle Inks with Traditional Printing Processes 

Dr Michael Mastropietro, 

PChem Associates Inc. , Co-founder / Director of R&D, United States 

With the price of silver doubling in the last six months there is increasing pressure on functional printers trying to maintain their profit margins while meeting their 

customers? price targets. PChem?s silver nanoparticle based inks enable the cost effective printing of highly conductive patterns using traditional methods such as 

flexography and screen printing. The nanoparticles sinter into foil like structures with continuous metallic paths between the particles resulting in much lower volume 

resistivity compared to conventional polymer thick film (PTF) silver flake based inks. This makes it possible to minimize the amount of silver used relative to PTF inks while 

maintaining performance. Mild curing temperatures and short residence times are necessary to process the inks allowing the use of lower cost substrates and higher press 

speeds. These factors allow for reductions in manufacturing and materials costs for the printed conductor portion of smart packages and electronic devices. 

Further, the ability to print very thin films which maintain uniform conductivity enables higher resolution patterning then previously possible with these print methods. 

Features sizes of 25 microns have been produced repeatedly under manufacturing conditions and the feasibility of higher resolutions demonstrated with flexographic 

printing. The ability to print much thinner films with significantly lower surface roughness while maintaining equivalent sheet resistance to PTF can also lead to mechanical 

performance advantages in the finished product constructions. All of these capabilities can be easily scaled to the production of large areas as these printing methods are 

commonly used for this purpose in graphic communication production. 

The general properties and processing requirements of PChem?s silver nanoparticle based flexo and screen inks as well as printed results on various substrates will be 

discussed. The commercial advantages of using nanoparticle based conductive inks including process ability, electrical and mechanical properties, and economic viability 

will be presented.

Novel Process Concepts (04:30 pm - 06:00 pm) | LOCATION HARMONIE E / LEVEL C2 

04:30 pm Inkjet Printing of Functional Materials on Selectively Plasma Treated Surfaces 

Mr Martijn van Dongen, 

Fontys University of Applied Sciences, PhD-student, Netherlands 

The Fontys Expertise Centre of Functional Polymers is a research centre which focuses among others on inkjet printing of functional materials for organic electronics. A 

large part of this research is directed to understanding the wetting behaviour of these materials on foils. µPlasma printing is a newly developed technology from InnoPhysics 

b.v.. µPlasma printing makes it possible to selectively change the wetting behaviour of substrates by integrating a multinozzle plasma printhead in an inkjet printer base 

system. By combining this technology with digital on demand printing techniques, like inkjet printing, new possibilities arise. Through selective changing local wetting 

behaviour on a substrate and inkjet printing on the plasma treated surface, it should be possible to print more accurate patterns with sharper lines and higher resolution. 

This paper will discuss two on-going investigations. First we will discuss a method to determine the resolution of a µPlasma printed single line. A method is devised to 

accurately determine the linewidth of a µPlasma printed single line for different plastic substrates and plasma doses. By looking at localized changes in wetting behaviour, 

using accurate drop placement from inkjet printing, the µPlasma print resolution will be determined. The second investigation looks at the alignment of µPlasma printed 

patterns together with inkjet printed patterns. The wetting behaviour of functional inks at the interface of a plasma treated / untreated surfaces is investigated to determine if 

plasma treatment benefits sharper and more accurate patterns for inkjet printing.

05:00 pm Selective Coating and Removal Technologies to Produce Patterned Films for Printed Electronics 

Mr Greg Gibson, 

nTact/FAS , President & CTO , United States 

Liquid chemistries are used to create a wide variety of functional layers in organic electronics. These materials are often deposited in the desired areas within the device 

structure using direct patterning methods. Alternately, these materials may be deposited over the entire substrate using a ?full coverage? coating method, and later partially 

removed to form the desired pattern. Direct patterning 

techniques offer the clear vantage of placement of the material in the desired location in a single step. However, existing techniques have some disadvantages, including 

direct contact with the substrate, relatively low throughput, roughness of the deposited film, and yield loss due to defects. Full 

coverage coating techniques can be used to produce a high quality film, but to generate the desired 

pattern subsequent steps such as photolithography or laser ablation are typically required, thus adding cost and complexity to the device fabrication process. 

nTact/FAS has developed a new set of technologies that combines an enhanced method of extrusion coating with a novel coating removal technique to produce patterned 

films. The Selective Coating method uses a specially designed extrusion coating die with multiple openings to define coated and 

uncoated areas (stripes) across the width of the substrate. This stripe coating method is combined with the ability to precisely start and stop the coating multiple times down 

the length of the substrate, thus 

enabling the deposition of an array of rectangular shapes. The Selective Removal technique uses a proprietary mechanism to remove portions of the coating immediately 

after deposition. The removal technique is non-contact, and has been successfully demonstrated to generate both rectilinear and 

complex shapes for a wide variety of coating materials. The coating edge profile after Selective Removal is sharp and well defined, comparing favorably with the edge of 

the initial coated film. Selective Coating and Selective Removal can be used independently or in conjunction, providing a unique and versatile means of adapting to process 

requirements.

05:20 pm Roll-to-Roll process concepts for general OLED lighting 

Dr Stefan Mogck, 

Fraunhofer Institute of Photonic Microsystems, Germany 

OLED lighting on glass substrates has been successfully started the market entry. A novel approach has been started to develop high efficient small molecule OLED stack 

deposition on flexible webs in a roll-to-roll process as a major cost reducing step. Low cost metal foil as a substrate for the OLED device will allow significant cost reduction, 

will open up new degrees of freedom in design leading and will be competitive for general signage and lighting applications. Metal foils as a substrate for the deposition of 

organic light-emitting diodes with the doped charge transport layers, the so called p-i-n OLED technology, will allow a direct OLED deposition on the substrate with low 

operating voltage. Within the ?Center of Organic Materials and Electronic Devices Dresden? (COMEDD) of Fraunhofer IPMS a roll-to-roll line for research and development 

for OLED lighting is currently going into operation. The roll-to-roll line consists of a vacuum coater for small molecule depositions, a roll-to-roll encapsulation under inert 

atmosphere and an optical inspection system for defect analysis. 

In this talk we will highlight the roll-to-roll OLED fabrication concepts and results from substrate patterning to the encapsulation process. Especially, the challenging inert 

transfer between the vacuum deposition and encapsulation process will be presented. Additionally, first results of roll-to-roll defect monitoring to control the roll-to-roll line 

will be outlined. The defect prevention is essential for the device performance to avoid electrical shorts and reduced luminous efficacy.

05:40 pm A New Method for Substrate Transport in Vacuum Deposition and In-Line Processes 

Mr Geert van der Zalm, 

Bosch Rexroth, Business Development Manager, Germany 

When a vacuum deposition process is combined with in-line transport, significant benefits in throughput can result compared to a cluster tool approach. The major 

challenge in making this approach successful is to design a motion system that has low particle generation, is modular, able to deal with the high vacuum levels, and still 

provides good serviceability. Traditional methods using conveyor belts, linear motors, or feedthrough couplings are not able to meet these challenges at an attractive cost. 

With the patented Linear Motion System (LMS), Bosch Rexroth provides a unique method to address all these challenges. Based on an ?inverted linear motor?, its principle 

is that magnet plates move in the vacuum environment, whereas the coils and measurement system are outside the vacuum. With proprietary coil control and sensor 

algorithms, the magnet plates can be controlled very accurately and independently. This results in a transport system that is very flexible, has no moving cables and 

virtually no maintenance requirements on the moving parts. By simply adding more coils and magnet plates, the system is expandable and modular. The Linear Motion 

System has been successfully used in numerous applications for a.o. solar deposition and hard disk sputtering. 

Main topics of the presentation are the discussion of the challenges of vacuum transport, an explanation of the physical principle behind this new technology, and a closer 

look at a sample application.
