Abstract: Embodiments of the present disclosure generally relate to apparatus and methods for semiconductor processing, more particularly, to a thermal process chamber. The thermal process chamber includes a substrate support, a first plurality of heating elements disposed over or below the substrate support, and a spot heating module disposed over the substrate support. The spot heating module is utilized to provide local heating of cold regions on a substrate disposed on the substrate support during processing. Localized heating of the substrate improves temperature profile, which in turn improves deposition uniformity.

Abstract: Embodiments described herein relate to a method of epitaxial deposition of p-channel metal oxide semiconductor (MMOS) source/drain regions within horizontal gate all around (hGAA) device structures. Combinations of precursors are described herein, which grow of the source/drain regions on predominantly <100> surfaces with reduced or negligible growth on <110> surfaces. Therefore, growth of the source/drain regions is predominantly located on the top surface of a substrate instead of the alternating layers of the hGAA structure. The precursor combinations include a silicon containing precursor, a germanium containing precursor, and a boron containing precursor. At least one of the precursors further includes chlorine.

Abstract: A master controller determines a first flow setpoint for a process flow gas and/or a carrier gas flow through a first mass flow controller. The master controller obtains a back pressure setpoint of a distribution manifold and determines a second flow setpoint for the process gas flow and/or the carrier gas flow through a second mass flow controller or a back pressure controller based on the determined first flow setpoint and the obtained back pressure setpoint. The master controller controls the process gas flow and/or the carrier gas flow through the first mass flow controller to the first flow setpoint and the second mass flow controller and/or the back pressure controller to the second flow setpoint. The master controller controls the back pressure of the distribution manifold to the back pressure set point in view of a back pressure reading from a back pressure sensor of the distribution manifold.
