Abstract: Apparatus and methods to process one or more wafers are described. A first processing station has a first gas flow pattern from one or more of a first gas diffuser, a first cooling channel pattern, or a first heater. A second processing station has a second gas flow pattern from one or more of a second gas diffuser, a second cooling channel pattern, or a second heater. The second gas diffuser, the second cooling channel pattern, or the second heater is rotated or translated relative to the first gas diffuser, the first cooling channel pattern, or the first heater to provide the second gas flow pattern complementary to the first gas flow pattern.

Abstract: Embodiments disclosed herein generally relate to a chamber liner for the high temperature processing of substrates in a processing chamber. The processing chamber utilizes an inert bottom purge flow to shield the substrate support from halogen reactants such that the substrate support may be heated to temperatures greater than about 650 degrees Celsius. The chamber liner controls a flow profile such that during deposition the bottom purge flow restricts reactants and by-products from depositing below the substrate support. During a clean process, the bottom purge flow restricts halogen reactants from contacting the substrate support. As such, the chamber liner includes a conical inner surface angled inwardly to direct purge gases around an edge of the substrate support and to reduce deposition under the substrate support and the on the edge.

Abstract: Apparatus and methods to process one or more wafers are described. A processing chamber comprises a first processing station comprising a first gas injector having a first face, a first emissivity and a first temperature, a second processing station comprising a second gas injector having a second face, a second emissivity and a second temperature, and a substrate support assembly comprising a plurality of substantially coplanar support surfaces, the substrate support assembly configured to move the support surfaces between the first processing station and the second processing station. When a wafer is on the support surfaces, a temperature skew of less than about 0.5° C. is developed upon moving the wafer between the stations in about 0.5 seconds.

Abstract: Apparatus and methods to process one or more wafers are described. A spatial deposition tool comprises a plurality of substrate support surfaces on a substrate support assembly and a plurality of spatially separated and isolated processing stations. The spatially separated isolated processing stations have independently controlled temperature, processing gas types, and gas flows. In some embodiments, the processing gases on one or multiple processing stations are activated using plasma sources. The operation of the spatial tool comprises rotating the substrate assembly in a first direction, and rotating the substrate assembly in a second direction, and repeating the rotations in the first direction and the second direction until a predetermined thickness is deposited on the substrate surface(s).
