    Abstract: Methods of depositing improved quality silicon nitride (SixNy) films are disclosed. Exemplary methods include exposing a semiconductor substrate in a semiconductor processing chamber to a silicon-containing precursor, to a first plasma produced from a first gas mixture comprising helium (He) and nitrogen (N2), the first gas mixture comprising a ratio of helium:nitrogen in a range of from 20:1 to 1000:1, and exposing the semiconductor substrate to a second plasma produced from a second gas mixture comprising helium (He), nitrogen (N2), and ammonia (NH3).

    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).
