    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).

    Abstract: Apparatus and methods for depositing a film in a PECVD chamber while simultaneously flowing a purge gas from beneath a substrate support are provided herein. In embodiments disclosed herein, a combined gas exhaust volume circumferentially disposed about the substrate support, below a first volume and above a second volume, draws processing gases from the first volume down over an edge of a first surface of the substrate support and simultaneously draws purge gases from the second volume upward over an edge of a second surface of the substrate support. The gases are than evacuated from the combined exhaust volume through an exhaust port fluidly coupled to a vacuum source.

    Abstract: A process chamber is provided including a sidewall, a substrate support having an outer ledge, and a gas inlet beneath the substrate support. The process chamber further includes a first liner disposed around a bottom surface of the outer ledge of the substrate support. The first liner has an inner surface separated from the outer ledge of the substrate support by a first gap. The process chamber further includes a flow isolator ring having an inner bottom surface disposed on the outer ledge of the substrate support and an outer bottom surface extending outwardly relative to the inner bottom surface, the outer bottom surface overlying the first gap.
