  • Publication number: 20250014938
    Abstract: Improved edge rings with flow conductance features are disclosed. The flow conductance features of the edge ring are features added to the edge ring that adjust the flow conductance of gas flowing in the local area of the edge ring. The flow conductance features can adjust the flow conductance to compensate for features on a semiconductor wafer, the edge ring, and in the chamber that may affect the flow of gas in the local areas. The flow conductance may be increased, reduced, or tuned depending on the desired effect.

  • Patent number: 11584993
    Abstract: Gas distribution assemblies and methods for providing a flow of gases to a process station are described. The gas distribution assemblies comprise a pumping liner with a showerhead and a gas funnel positioned therein. The pumping liner has an inner wall that slants at a first angle relative to a central axis of the gas distribution assembly so that the inner wall adjacent the bottom wall of the pumping liner is closer to the central axis than the inner wall adjacent the top wall. The gas funnel and pumping liner form a plenum between the outer wall of the gas funnel, a cavity in the bottom wall of the gas funnel and the inner wall of the pumping liner.
