    Abstract: An apparatus as disclosed herein relates to a chamber body design for use within a thermal deposition chamber, such as an epitaxial deposition chamber. The chamber body is a segmented chamber body design and includes an inject ring and a base plate. The base plate includes a substrate transfer passage and one or more exhaust passages disposed therethrough. The inject ring includes a plurality of gas inject passages disposed therethrough. The inject ring is disposed on top of the base plate and attached to the base plate. The one or more exhaust passages and the gas inject passages are disposed opposite one another. One or more seal grooves are formed in both the base plate and the inject ring to enable the inject ring and the base plate to seal to one another as well as other components within the process chamber.

    Abstract: A master controller identifies a flow ratio setpoint for at least one of a process gas or a carrier gas flow to a process chamber through a set of mass flow controllers. The master controller determines a flow setpoint for the at least one of the process gas or the carrier gas through the set of mass flow controllers based on the identified flow ratio setpoint. The master controller controls the at least one of the process gas flow or the carrier gas flow through each of the set of mass flow controllers according to the determined flow setpoint for each of the set of mass flow controllers and based on a back pressure reading provided by a back pressure sensor.

    Abstract: Embodiments described herein generally relate to a substrate processing system, such as an etch processing system. In one embodiment, a method of processing a substrate is disclosed herein. The method includes removing a native oxide from a surface of the substrate, baking the substrate in a pre-treatment thermal chamber such that double atomic steps are formed on the surface of the substrate, and forming an epitaxial layer on the substrate after the substrate is baked.
