Patent ID: 8044594

Claim:
A plasma processing system comprising, a plasma chamber; a power generator comprising an output adapted to supply a power signal to the plasma chamber; a feedback component comprising, at least one input, each of the at least one inputs adapted to receive at least one first signal having a first signal level dependent upon the power signal, and an output adapted to emit a second signal having a second signal level; and a controller adapted to, receive the second signal, and supply a third signal to the power generator, the third signal, having a third signal level dependent upon the second signal level, and configured to control the power generator to, supply the power signal at a power level comprising a first power level and a first voltage level for a particular processing application, one of reduce and remove the power from the plasma processing chamber, increase, subsequent to the power being one of reduced and removed, the voltage level until the power level reaches a threshold level, and modulate, subsequent to the threshold level being reached, the voltage until the voltage level returns to the first voltage level.
