Abstract: The present disclosure relates to methods of adjusting uniformity for substrate processing, and related apparatus and systems, for semiconductor manufacturing. In one or more embodiments, a heating power applied to a set of one or more heat sources is adjusted by an adjustment factor. In one or more embodiments, a method of adjusting uniformity. The method includes scanning a sensor across one or more sections to take a plurality of readings, generating a signal profile including the plurality of readings, and analyzing the signal profile by comparing the signal profile to a range. The method includes adjusting one or more heating parameters if at least one portion of the signal profile is outside of the range. The adjusting includes identifying a set of one or more heat sources that correlate with the at least one portion of the signal profile, and adjusting a heating power by an adjustment factor.

Abstract: The present disclosure generally relates to a process chamber for processing of semiconductor substrates. The process chamber includes an upper lamp assembly, a lower lamp assembly, a susceptor, an upper window disposed between the substrate support and the upper lamp assembly, a lower window disposed between the lower lamp assembly and the substrate support, an inject ring, and a base ring. The susceptor includes a movement assembly. The movement assembly includes a bearing feedthrough assembly. The bearing feedthrough assembly is a ferrofluidic feedthrough assembly and functions as a ferrofluidic bearing. The bearing feedthrough assembly includes a shaft coupled to the support shaft. The shaft is rotated within the bearing feedthrough assembly. The bearing feedthrough assembly is combined with a first linear spline and a second linear spline.

Abstract: Embodiments described herein include processes and apparatuses relate to epitaxial deposition. A method for epitaxially depositing a material is provided and includes positioning a substrate on a substrate support surface of a susceptor within a process volume of a chamber body, where the process volume contains upper and lower chamber regions. The method includes flowing a process gas containing one or more chemical precursors from an upper gas inlet on a first side of the chamber body, across the substrate, and to an upper gas outlet on a second side of the chamber body, flowing a purge gas from a lower gas inlet on the first side of the chamber body, across the lower surface of the susceptor, and to a lower gas outlet on the second side of the chamber body, and maintaining a pressure of the lower chamber region greater than a pressure of the upper chamber region.
