Classification: CPC H  C | IPC C  H

Claim 0:
1. A method comprising:
powering a first power source connected to a first plasma gas port in a first process region of a processing chamber, the first power source directly coupled to a first match circuit, and the first match circuit directly connected to the first plasma gas port, the first plasma gas port generating a first plasma with a first phase;
powering a second power source connected to a second plasma gas port in a second process region different from the first process region of the processing chamber; the second power source directly coupled to a second match circuit, and the second match circuit directly connected to the second plasma gas port, the second plasma gas port generating a second plasma with a second phase; and
controlling the first phase or the second phase using a master exciter directly connected to the first power source, and the second power source, the first match circuit and the second match circuit.
