    摘要: Embodiments of the present invention generally relate to apparatus for reducing arcing and parasitic plasma in substrate processing chambers. The apparatus generally include a processing chamber having a substrate support, a backing plate, and a showerhead disposed therein. A showerhead suspension electrically couples the backing plate to the showerhead. An electrically conductive bracket is coupled to the backing plate and spaced apart from the showerhead. The electrically conductive bracket may include a plate, a lower portion, an upper portion, and a vertical extension. The electrically conductive bracket contacts an electrical isolator.

    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.
