Abstract:
A plasma reactor system for processing a substrate, the plasma reactor comprising:a processing chamber for containing a plasma, the plasma comprising at least one plasma product for processing the substrate; a gas inlet coupled to the processing chamber for providing gas to the processing chamber; a first power source; an induction coil outside of the processing chamber, coupled to the first power source, to couple power from the first power source into the processing chamber to sustain the plasma; a plasma shaping member positioned within the processing chamber, the plasma shaping member having a recessed portion substantially above the center of the substrate and an extended portion outside the recessed portion, wherein the electrical potential of the plasma shaping member is floating relative to ground during processing of the substrate; and a support for the substrate positioned such that the substrate is exposed to the at least one plasma product during processing.
