Abstract:
Methods of semiconductor processing may include performing a process on a semiconductor substrate. The semiconductor substrate may be seated on a substrate support positioned within a processing region of a semiconductor processing chamber. The methods may include flowing a first backside gas through the substrate support at a first flow rate. The methods may include removing the semiconductor substrate from the processing region of the semiconductor processing chamber. The methods may include performing a plasma cleaning operation within the processing region of the semiconductor processing chamber. The methods may include flowing a second backside gas through the substrate support at a second flow rate. At least a portion of the second backside gas may flow into the processing region through accesses in the substrate support.
