Particle-in-cell simulations of hollow cathode enhanced capacitively coupled radio frequency discharges

Lafleur, T.; Boswell, R. W.


A two-dimensional particle-in-cell simulation has been developed to study density enhancement of capacitively coupled rf discharges with multi-slit electrodes. The observed density increase is shown to result from a hollow cathode effect that takes place within the multi-slit electrode configuration, which forms as a result of secondary electron emission due to ion bombardment. By investigating the ionization and power deposition profiles, it is found that rfsheathheating is too weak to sustain...[Show more]
