Abstract: A method of forming a silicon germanium layer on a surface of a substrate and a system for forming a silicon germanium layer are disclosed. Examples of the disclosure provide a method that includes providing a plurality of growth precursors to control and/or promote parasitic gas-phase and surface reactions, such that greater control of the film (e.g., thickness and/or composition) uniformity can be realized.

Abstract: A chamber arrangement has a chamber body with upper and lower walls. A substrate support is arranged within an interior of the chamber body and supported for rotation about a rotation axis. An upper heater element array is supported above the upper wall and a lower heater element array supported below the lower wall. A pyrometer is supported above the upper heater element array, is optically coupled to the interior of the chamber body, and is operably connected to the upper heater element array. A thermocouple is arranged within the interior of the chamber body, is in intimate mechanical contact with the substrate support, and is operably connected to the lower heater element array. Semiconductor processing systems and material layer deposition methods are also described.

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.

Abstract: A reactor system may comprise a first reaction chamber and a second reaction chamber. The first and second reaction chambers may each comprise a reaction space enclosed therein, a susceptor disposed within the reaction space, and a fluid distribution system in fluid communication with the reaction space. The susceptor in each reaction chamber may be configured to support a substrate. The reactor system may further comprise a first reactant source, wherein the first reaction chamber and the second reaction chamber are fluidly coupled to the first reactant source at least partially by a first reactant shared line. The reactor system may be configured to deliver a first reactant from the first reactant source to the first reaction chamber and a second reaction chamber through the first reactant shared line.

Abstract: Methods and systems for forming structures including one or more layers comprising silicon germanium and one or more layers comprising silicon are disclosed. Exemplary methods can include using a surfactant, using particular precursors, and/or using a transition step to improve an interface between adjacent layers comprising silicon germanium and comprising silicon.
