Patent ID: 7285916

Claim:
A multi-chamber plasma process system, comprising: a plurality of process chambers, each including a susceptor and an inductively coupled plasma generator having an ignition electrode; a main power supply for supplying radio frequency (RF) power for generating plasma to each said inductively coupled plasma generator; a first impedance matcher connected between the main power supply and each said inductively coupled plasma generator; an ignition power supply supplied with the RF power from the main power supply, and supplying ignition power to the ignition electrode provided in each said inductively coupled plasma generator; a plurality of bias power sources for supplying bias power to the susceptors provided in the plurality of process chambers; a plurality of second impedance matchers connected between the susceptors provided in the plurality of process chambers and the bias power sources supplying bias power to the susceptors; and a controller for controlling the first impedance matcher, the plurality of second impedance matchers, and the ignition power supply.
