    Abstract: A method and apparatus for processing a substrate are described herein. The methods and apparatus described enable a chemical vapor deposition (CVD) chamber to process substrates (also referred to as wafers herein) at different temperatures. The processing chamber includes a chamber body, a substrate support disposed within the chamber body and having a top surface, a plurality of substrate lift pins disposed through the substrate support, and a shadow ring lift assembly. The shadow ring lift assembly is operable to raise and lower a shadow ring positioned above or level with the top surface of the substrate support.

    Abstract: A method of forming a silicon nitride film includes: preparing a substrate in a processing container, the substrate having a graphene film on a surface of the substrate; supplying a nitrogen-containing gas into the processing container; supplying a Si precursor gas into the processing container after the nitrogen-containing gas is supplied and after a pressure control inside the processing container is stabilized; generating plasma within the processing container by supplying radio-frequency power for plasma generation after the Si precursor gas is supplied and before the pressure control inside the processing container is stabilized; and forming the silicon nitride film on the graphene film by exposing the substrate to the plasma.

    Abstract: A method for processing a substrate is provided, wherein the substrate is located below a showerhead in a processing chamber. A deposition layer is deposited on the substrate, wherein at least one deposition gas is provided through the showerhead. A secondary purge gas is flowed during the depositing the deposition layer from a location outside of the showerhead in the processing chamber forming a flow curtain around an outer edge of the showerhead, wherein the secondary purge gas comprises at least one component gas. A partial pressure of the at least one component gas is changed over time during the depositing the deposition layer, wherein the depositing the deposition layer has a non-uniformity, wherein the changing the partial pressure changes the non-uniformity over time during the depositing the deposition layer.
