Abstract

A plasma process machine includes at least two electrodes disposed in a processing chamber and in contact with targets, an alternating current source connected to supply power to the electrodes, and a power delivery controller adapted to control power delivered by the alternating current source to the electrodes. The power delivery controller is configured to determine a control value from a comparison between actual power delivery as detected by a detector and a desired power delivery, and to adjust power delivery based on the control value.
