Abstract: A fixture is provided. The fixture includes a base, a turntable, a first sensor, and a second sensor. The turntable is supported on the base, is rotatable about a rotation axis, and is configured to slidably seat a susceptor assembly for rotation about the rotation axis. The first sensor is fixed relative to the base, is radially offset from the rotation axis, and is configured to determine ex-situ runout of the susceptor assembly. The second sensor is fixed relative to the first sensor, is axially offset from the first sensor, and is configured to determine ex-situ wobble of the susceptor assembly. Fixture arrangements and methods of determining ex-situ runout and ex-situ wobble of susceptor assemblies for semiconductor processing systems are also described.

Abstract: Exemplary semiconductor processing systems may include an output manifold that defines at least one plasma outlet. The systems may include a gasbox disposed beneath the output manifold. The gasbox may include an inlet side facing the output manifold and an outlet side opposite the inlet side. The gasbox may include an inner wall that defines a central fluid lumen. The inner wall may taper outward from the inlet side to the outlet side. The systems may include an annular spacer disposed below the gasbox. An inner diameter of the annular spacer may be greater than a largest inner diameter of the central fluid lumen. The systems may include a faceplate disposed beneath the annular spacer. The faceplate may define a plurality of apertures extending through a thickness of the faceplate.

Abstract: 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.
