    Abstract: A semiconductor processing system includes a precursor delivery arrangement, a chamber arrangement, and a controller. The chamber arrangement is connected to the precursor delivery arrangement. The controller is operatively connected to the precursor delivery arrangement and the chamber arrangement, includes a processor disposed in communication with a memory, and is responsive to instructions recorded on the memory to acquire a baseline substrate thickness profile for a selected process recipe, determine a first temperature profile setting for depositing a first material layer at low pressure for the selected process recipe, determine a high-pressure thermal offset for the first temperature profile setting, apply the high-pressure thermal offset to the first temperature profile setting to determine a second temperature profile setting, seat a first substrate on the first substrate support within the chamber arrangement and flow a second material layer precursor via the precursor delivery arrangement over the first substrate at high pressure according to the selected process recipe using the second temperature profile setting.

    Abstract: A method of depositing an epitaxial material layer using pyrometer-based control. The method includes cleaning a reaction chamber of a reactor system, and, after the cleaning, providing a substrate within the reaction chamber. The method includes stabilizing a temperature of the substrate relative to a target deposition temperature. During stabilization, the heater assembly is operated with control signals to operate heaters in the heater assembly that are generated based on a direct measurement of the temperature of the substrate, such as with one to three pyrometers. The method includes, after the stabilizing of the temperature of the substrate, depositing an epitaxial material layer on a surface of the substrate. Then, for an additional number of substrates, the method involves repeating the steps of providing a substrate within the reaction chamber, stabilizing the temperature of the substrate, and depositing an epitaxial material layer on the substrate followed by another chamber cleaning.
