    摘要： A plasma processing system is provided. The plasma processing system includes a radio frequency (RF) power generator configured to have a tunable frequency power output, the frequency output being adjustable within a range. A processing chamber having a bottom electrode and a top electrode is included. A plasma region being defined between the bottom and top electrodes and the processing chamber receives RF power from the RF power generator. A match network is coupled between the RF power generator and the processing chamber. The match network has a first tunable element and a second tunable element. The first tunable element adjusts a split between a first grounding pathway defined within an inner region of the plasma region and a second grounding pathway defined within an outer region of the plasma region. The second tunable element adjusts a load delivered to the processing chamber from the power generator.

    摘要： A plasma processor processing a workpiece includes sources having frequencies 2 MHz, 27 MHz, and 60 MHz, applied by three matching networks to an electrode in a vacuum chamber including the workpiece. Alternatively 60 MHz is applied to a second electrode by a fourth matching network. The matching networks, substantially tuned to the frequencies of the sources driving them, include series inductances so the 2 MHz inductance exceeds the 27 MHz network inductance, and the 27 MHz network inductance exceeds the inductances of the 60 MHz networks. The matching networks attenuate by at least 26 DB the frequencies of the sources that do not drive them. Shunt inductors between the 27 and 60 MHz sources decouple 2 MHz from the 27 and 60 MHz sources. A series resonant circuit (resonant to about 5 MHz) shunts the 2 MHz network and the electrode to help match the 2 MHz source to the electrode.

    摘要： The present invention relates generally to plasma processing and, more particularly, to plasma processing chambers and electrode assemblies used therein. According to one embodiment of the present invention, an electrode assembly is provided comprising a thermal control plate, a silicon-based showerhead electrode, and a thermally conductive gasket, wherein respective profiles of a frontside of the thermal control plate and a backside of the showerhead electrode cooperate to define a disjointed thermal interface comprising portions proximal to showerhead passages of the showerhead electrode and portions displaced from the showerhead passages. The displaced portions are recessed relative to the proximal portions and are separated from the showerhead passages by the proximal portions of the thermal interface. The gasket is positioned along the displaced portions such that the gasket is isolated from the showerhead passages and may facilitate heat transfer across the thermal interface from the showerhead electrode to the thermal control plate.
