Abstract:
1. A method for processing a substrate, comprising: providing a chamber wall defining a main cavity with an opening; providing a cover across the opening, wherein the cover comprises: supporting an electrode by a region of the first section, where the electrode extends into the main cavity from the first section, wherein support of the second section by the first section is not above support of the electrode by the first section, wherein the pocket extends between the first section and the second section above the region of the first section upon which the electrode is supported so that the first section separates the electrode and the pocket; placing the substrate within the main cavity; evacuating gas from the main cavity through an exhaust port, so that the second section deforms; using the pocket to reduce the deformation of the first section; introducing a processing gas into the main cavity; using the electrode to transform the processing gas into a plasma; and using the plasma to process the substrate.
