Moveable edge coupling ring for edge process control during semiconductor wafer processing
Abstract:
A substrate processing system includes a processing chamber and a pedestal arranged in the processing chamber. An edge coupling ring is arranged adjacent to a radially outer edge of the pedestal. A first actuator is configured to selectively move the edge coupling ring to a raised position, relative to the pedestal to provide clearance between the edge coupling ring and the pedestal to allow a robot arm to remove the edge coupling ring from the processing chamber.
