    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.
