    摘要: A fixture includes a frame, a leveling plate, a bracket, and a laser profiler. The frame is arranged for fixation above a reaction chamber arranged to deposit a film onto a substrate. The leveling plate is supported on the frame. The bracket is supported on the leveling plate. The laser profiler is suspended from the bracket, overlays the reaction chamber, and has a field of view that extends through the leveling plate and the frame to determine position of a target within the reaction chamber. Semiconductor processing systems and methods of determining position of targets within reaction chambers in semiconductor processing systems are also described.

    摘要: A method of forming a structure includes supporting a substrate within a reaction chamber of a semiconductor processing system, the substrate having a recess with a bottom surface and a sidewall surface extending upwards from the bottom surface of the recess. A film is deposited within the recess and onto the bottom surface and the sidewall surface of the recess, the film having a bottom segment overlaying the bottom surface of the recess and a sidewall segment deposited onto the sidewall surface of the recess. The sidewall segment of the film is removed while at least a portion bottom segment of the film is retained within the recess, the sidewall segment of the film removed from the sidewall surface more rapidly than removing the bottom segment of the film from the bottom surface of the recess. Semiconductor processing systems and structures formed using the method are also described.

    摘要: A substrate support and lift assembly configured to support and lift a substrate from a susceptor is disclosed. The substrate support and lift assembly can include a susceptor support and a lift pin. The susceptor support can be configured to support the susceptor thereon. The susceptor support includes a plurality of support arms each extending radially from a central portion of the susceptor support to a terminus. Each of the plurality of support arms includes an aperture extending therethrough. The lift pin can be configured to fit through the aperture of a corresponding support arm to lift a substrate on the susceptor.

    摘要: A susceptor for semiconductor substrate processing is disclosed herein. In some embodiments, the susceptor may comprise an inner susceptor portion and an outer susceptor portion. The susceptor portions may self-align via complementary features, such as tabs on the outer susceptor and recesses on the inner susceptor portion. The inner susceptor portion may contain several contact pads with which to support a wafer during semiconductor processing. In some embodiments, the contact pads are hemispherical to reduce contact area with the wafer, thereby reducing risk of backside damage. The inner susceptor portion may contain a cavity with which to receive a thermocouple. In some embodiments, the diameter of the cavity is greater than the diameter of the thermocouple such that the thermocouple does not contact the walls of the cavity during processing, thereby providing highly accurate temperature measurements.
