Abstract: |
|||
| A method and system for controlling electron densities in a plasma processing system (105). By applying a dither voltage (117) and a correction voltage to a voltage-controller oscillator (101), electron density of an open resonator plasma processing system (105) may be measured and controlled as part of a plasma-based process. | |||
