Abstract:
A power delivery system for providing energy to sustain a plasma in a plasma processing chamber configured for processing substrates, comprising:a metallic enclosure having an input port, a first output port, a second output port, and a third output port;a power distribution box disposed within said enclosure, said power distribution box including a first AC input port for receiving AC power from external of said metallic enclosure through said input port and for providing AC power to AC loads external to said metallic enclosure via said first output port;a DC power supply electrically coupled to said power distribution box, said DC power supply being configured to receive said AC power from said power distribution box and to output DC power, said DC power supply being disposed within said metallic enclosure, said DC power being supplied to DC loads external of said metallic enclosure via said second output port;a first RF generator electrically coupled to said power distribution box to receive said AC power, said first RF generator being coupled with said DC power supply to receive said DC power, said first RF generator being disposed within said metallic enclosure; anda first match network electrically coupled with an output of said first RF generator to receive RF energy from said first RF generator, said first match network having a first match network output for providing first matched RF energy to a first electrode of said plasma processing chamber via said third output port, said first match network being disposed within said metallic enclosure, wherein no other RF generator associated with said plasma processing chamber exists outside said metallic enclosure.
