Magnetron Sputtering – a magnetic field applied at right angles to the E-field; causes e- to follow spiral paths, increases probability of ionizing a gas atom, increases ionization efficiency, confines plasma resulting in a higher deposition rate; also able to form plasma at lower chamber pressures Figure 12.17 Planar and cylindrical magnetron sputtering systems T: target; P: plasma; SM: solenoid; M: magnet; E: electric field; B: magnetic field (after Wasa and Hayakawa, reprinted by permission, Noyes Publications).
