Abstract: A substrate retaining apparatus, a load lock assembly comprising the substrate retaining apparatus, and a system including the substrate retaining apparatus are disclosed. The substrate retaining apparatus can include at least one sidewall and one or more heat shields. One or more of the at least one sidewall can include a cooling fluid conduit to facilitate cooling of substrates retained by the substrate retaining apparatus. Additionally or alternatively, one or more of the at least one sidewall can include a gas conduit to provide gas to a surface of a retained substrate.

Abstract: An arrangement of linear heat lamps is provided which allows for localized control of temperature nonuniformities in a substrate during semiconductor processing. A reactor includes a substrate holder positioned between a top array and a bottom array of linear heat lamps. At least one lamp of the arrays includes a filament having a varying density and power output along the length of the lamp. In particular, at least one lamp of the arrays includes a filament having a higher filament winding density within a central portion of the lamp relative to peripheral portions of the lamp. In some embodiments, the at least one lamp is a central lamp extending across a central portion of the substrate heated by the lamp. Furthermore, at least one lamp of the arrays has a higher power output within a central portion of the lamp than at peripheral portions of the lamp.

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.

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.
