Patent ID: 11887811
Assignee: APPLIED MATERIALS, INC.
Field: Semiconductors (Electrical engineering)
Classification: CPC H  C | IPC C  H

Claim 12:
13. A semiconductor processing system comprising:
a chamber body;
a substrate support configured to support a semiconductor substrate, wherein the substrate support comprises:
a pedestal having a shaft and a platen;

a cover plate, wherein:
the cover plate is coupled with the platen along a first surface of the cover plate;
the cover plate defines a recessed channel in a second surface of the cover plate opposite the first surface;
the cover plate defines at least one lateral channel that is disposed at a depth within the cover plate that is between a bottom surface of the recessed channel and the first surface; and
the cover plate defines a plurality of apertures that fluidly couple the at least one lateral channel with discrete portions of the recessed channel; and
a puck coupled with the second surface of the cover plate, the puck incorporating an electrode, wherein the puck defines a plurality of apertures extending vertically through the puck to fluidly access the recessed channel defined in the cover plate;

a faceplate, wherein the chamber body, the substrate support, and the faceplate define a processing region;
a high-frequency plasma source coupled with the faceplate; and
a low-frequency plasma source coupled with the substrate support.
