    Abstract: Embodiments of the invention generally provide methods for cleaning a UV processing chamber. In one embodiment, the method includes flowing an oxygen-containing gas through a plurality of passages formed in a UV transparent gas distribution showerhead and into a processing region located between the UV transparent gas distribution showerhead and a substrate support disposed within the thermal processing chamber, exposing the oxygen-containing gas to UV radiation under a pressure scheme comprising a low pressure stage and a high pressure stage to generate reactive oxygen radicals, and removing unwanted residues or deposition build-up from exposed surfaces of chamber components presented in the thermal processing chamber using the reactive oxygen radicals.

    Abstract: Variable orifice check valves comprising a flange with a guide pin, spring and movable plate are described. The flange has a body with at least one guide pin opening in the top surface. A guide pin is positioned within the at least one guide pin opening and a spring is positioned around the guide pin. The movable plate has an opening and slides along the guide pins with the spring between the top surface of the flange body and the bottom surface of the movable plate.

    Abstract: Embodiments of the present disclosure are related to directed to a pressure seal for a process chamber. The pressure seal comprises a bottom portion, a compressible middle portion on the bottom portion, and a top portion on the compressible middle portion. The disclosed pressure seal is configured to reduce pumping time of a process region in an interior volume of a processing chamber compared to a process chamber that does not include a pressure seal. Processing chambers including the disclosed pressure seal are configured to process a semiconductor substrate at high temperatures, such as a temperature of greater than or equal to 350° C. Methods of sealing a processing chamber using the disclosed pressure seal are also described.

    Abstract: Embodiments of the present disclosure are related to directed to a pump liner for a process chamber. The pump liner is aligned with particular components in the process chamber so that there is an upper gap and a lower gap between the pump liner and the particular processing chamber components (e.g., an edge ring). The pump liner advantageously reduces side to side variation in temperature and gas flow based on its alignment with particular components in the process chamber (e.g., the edge ring) and the size of the upper gap and the lower gap. Some embodiments advantageously provide better precursor flow distribution for various process spacing between the showerhead and wafer.
