A power delivery system for providing energy to sustain a plasma in a plasma processing chamber configured for processing substrates. The power delivery system includes a metallic enclosure (202) having an input port, a first output port, a second output port, and a third output port. There is further included a power distribution box (204) disposed within the enclosure. The power distribution box includes a first AC input port for receiving AC power from external of the metallic enclosure through the input port and for providing AC power to AC loads external to the metallic enclosure via the first output port. There is also included a DC power supply (220) electrically coupled to the power distribution box. The DC power supply is configured to receive the AC power from the power distribution box and to output DC power. The DC power supply is disposed within the metallic enclosure. The DC power is supplied to DC loads external of the metallic enclosure via the second output port. Additionally, there is included a first RF generator electrically coupled to the power distribution box to receive the AC power. The first RF generator is coupled with the DC power supply to receive the DC power. The first RF generator is disposed within the metallic enclosure. Further, there is included a first match network electrically coupled with an output of the first RF generator to receive RF energy from the first RF generator. The first match network has a first match network output for providing first matched RF energy to a first electrode of the plasma processing chamber via the third output port. The first match network is disposed within the metallic enclosure, wherein no other RF generator associated with the plasma processing chamber exists outside the metallic enclosure. <IMAGE> |
