    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: A susceptor can include a generally circular shape and may include an inner and outer susceptor. The outer susceptor can include a support region having one or more support mechanisms as well as a channel region extending from the region boundary to an outer radial boundary radially inward of an outer edge of the susceptor, the channel region can include a plurality of channels extending radially from the region boundary to the outer radial boundary.
    The inner susceptor can include a second plurality of channels extending from the inner radial boundary to an edge of the inner susceptor.
