Upper edge ring of a process kit for semiconductor substrate processing

Description

FIG. 1 is a top plan view of an upper edge ring of a process kit for semiconductor substrate processing, showing our new design.

FIG. 2 is a bottom plan view thereof.

FIG. 3 is a front elevation view thereof, the back, left, and right side elevation views are identical to the elevation view shown in FIG. 3.

FIG. 4 is a top isometric view thereof.
