Development of the Electronics Industry<br />
The electronics <strong>in</strong>dustry is a large, diverse <strong>in</strong>dustry which is made up<br />
of two major sectors: components <strong>and</strong> f<strong>in</strong>al products. The components -<br />
which are comb<strong>in</strong>ed <strong>in</strong>to f<strong>in</strong>al products -- can be further divided <strong>in</strong>to<br />
passive (e.g., capacitors, resistors) <strong>and</strong> active (e.g., semiconductors,<br />
tubes) components. The f<strong>in</strong>al products can be further divided <strong>in</strong>to consumer,<br />
<strong>in</strong>dustrial/scientific, <strong>and</strong> military/aero-space.<br />
The electronics <strong>in</strong>dustry has undergone a rapid technological change<br />
whi ch is best characteri zed by the semi conductor <strong>in</strong>dustry. Preceded by<br />
vacuum tubes s<strong>in</strong>ce the 1920s, the semiconductor <strong>in</strong>dustry fully emerged with<br />
the development of the transistor <strong>in</strong> the 1950s. And with the development of<br />
the <strong>in</strong>tegrated ci rcuit (Ie) <strong>and</strong> the growi ng dem<strong>and</strong> <strong>for</strong> computers <strong>in</strong> the<br />
earl y 1960s, the semi conductor <strong>in</strong>dustry began to mushroom. Other 1 arge,<br />
captive producers al so entered the competition. By the early 1970s there<br />
were 96 U.S. compani es produci ng semiconductors. These ranged from<br />
diversified corporations like Monsanto, to captive producers like Motorola,<br />
to merchant IC houses like National Semiconductor.<br />
Although the types of ICs are numerous, the producti on processes, all<br />
follow<strong>in</strong>g circuitry design, fall <strong>in</strong>to the same basic flow: (l) mask-mak<strong>in</strong>g,<br />
(2) wafer fabrication, (3) assembly, <strong>and</strong> (4) test<strong>in</strong>g (Oldham 1977). The<br />
mask-mak<strong>in</strong>g step is basically a photo-reduction process to reduce the size<br />
of the ci rcuit desi gn. Wafer fabri cati on represents the most compl ex <strong>and</strong><br />
sensitive of the processes, when slices of silicon crystals are doped with<br />
chemi cal impuriti es to create el ectroni cally conducti ve <strong>and</strong> non-conducti ve<br />
areas on each chip, the circuit pattern then be<strong>in</strong>g etched <strong>in</strong>to the wafers<br />
with acids <strong>and</strong> solvents. In the assembly stage, the wafers are cut <strong>in</strong>to<br />
i ndi vi dual chi ps, whi ch are then attached to substrates (or headers) <strong>and</strong><br />
bonded under microscope to the appropriate po<strong>in</strong>ts on the circuit. F<strong>in</strong>ally,<br />
the packaged devices are subjected to a series of temperature, leakage, <strong>and</strong><br />
electrical tests. The required work<strong>for</strong>ce <strong>for</strong> the production of<br />
semiconductors consists of a large number of talented scientists <strong>and</strong><br />
eng<strong>in</strong>eers <strong>and</strong> a large number of semi-skilled <strong>and</strong> unskilled production<br />
workers (U.S. Department of Commerce 1979).<br />
Because of rapid technological changes, the products of the<br />
semiconductor <strong>in</strong>dustry have a very short product cycle (Chang 1971). With<br />
constantly exp<strong>and</strong>i ng vol ume <strong>and</strong> improved technology, the prices of these<br />
products have also consistently <strong>and</strong> rapidly fallen after their <strong>in</strong>itial<br />
<strong>in</strong>troduction to the market. These reasons, along with the phenomenal growth<br />
<strong>in</strong> the number of manufacturers, cause the <strong>in</strong>dustry to be highly competitive<br />
<strong>in</strong> all countries. Cont<strong>in</strong>uous research, development, <strong>and</strong> capital <strong>in</strong>vestment<br />
<strong>in</strong> equipment are vital. Hence, the survival of any company essentially<br />
depends on the ability to <strong>in</strong>troduce new, superior products early <strong>and</strong> to keep<br />
the variable costs of production -- the majority of which is labor -- very<br />
low.<br />
Because the process <strong>for</strong> production of semiconductors can be segmented<br />
easily <strong>in</strong>to the four steps, because the products are small <strong>and</strong> lightweight,
