    摘要： A method of processing a workpiece in the chamber of a plasma reactor having a ceiling overlying the workpiece by introducing a process gas into the chamber through a gas distribution plate in the ceiling. The gas is introduced by distributing gas flow from a first gas input to plural gas distribution orifices extending through a manifold of the gas distribution plate, and distributing gas flow from each of the plural gas distribution orifices to plural gas injection orifices in a showerhead of the gas distribution plate. The method further includes restricting gas flow in the gas distribution plate to paths having arcuate lengths about an axis of symmetry less than a complete circle. The method also includes capacitively and inductively coupling plasma source power into the chamber through the gas distribution. The method further includes adjusting the plasma ion density radial distribution in the process region by adjusting the ratio between the amounts of the capacitively coupled VHF power and the inductively coupled power.

    摘要： Embodiments of the present invention provide apparatus and method for processing a substrate with increased uniformity. One embodiment of the present invention provides an apparatus for processing a substrate. The apparatus comprises a chamber body defining a processing volume, a substrate support disposed in the processing volume, a showerhead disposed in the processing volume opposite to the substrate support, and a plasma generation assembly configured to ignite a plasma from the processing gases in the processing gas in the processing volume. The showerhead is configured to provide one or more processing gases to the processing volume. The showerhead has two or more distribution zones each independently controllable.

    摘要： An RF blocking filter isolates a two-phase AC power supply from at least 2 kV p-p of power of an HF frequency that is reactively coupled to a resistive heating element, while conducting several kW of 60 Hz AC power from the two-phase AC power supply to the resistive heating element without overheating, the two-phase AC power supply having a pair of terminals and the resistive heating element having a pair of terminals. The filter includes a pair of cylindrical non-conductive envelopes each having an interior diameter between about one and two inches and respective pluralities of fused iron powder toroids of magnetic permeability on the order of about 10 stacked coaxially within respective ones of the pair of cylindrical envelopes, the exterior diameter of the toroids being about the same as the interior diameter of each of the envelopes. A pair of wire conductors of diameter between 3 mm and 3.5 mm are helically wound around corresponding ones of the pair of envelopes to form respective inductor windings in the range of about 16 to 24 turns for each the envelope, each of the conductors having an input end and an output end. The input end of each one of the conductors is coupled to a corresponding one of the pair of terminals of the two-phase AC power supply, and the output end of each one of the conductors is coupled to a corresponding one of the pair of terminals of the resistive heating element.
