Abstract: Exemplary semiconductor processing systems include a chamber body having sidewalls and a base. The systems may include a substrate support extending through the base. The substrate support may include a support plate defining lift pin locations and a shaft coupled with the support plate. The systems may include a shield coupled with the shaft and extending below the support plate. The shield may define a central aperture that extends beyond an outer periphery of the shaft. The systems may include a purge baffle coupled with the shield at a position that is beyond the central aperture such that a space between the purge baffle and the shaft is in fluid communication with a space between the shield and the support plate. The purge baffle may extend along at least a portion of the shaft. The systems may include a purge gas source coupled with the purge baffle.

Abstract: The present disclosure relates to a lid assembly apparatus and related methods for substrate processing chambers. In one implementation, a lid assembly includes a gas manifold. The gas manifold includes a first gas channel configured to receive a process gas, a second gas channel configured to receive a doping gas, and a third gas channel configured to receive a cleaning gas. The lid assembly also includes a showerhead. The showerhead includes one or more first gas openings that are configured to receive the process gas, and one or more second gas openings that are configured to receive the doping gas.
