Method and system for depositing epitaxial material layer

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 t...

Beschreibung
Zusammenfassung:	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.
