摘要： A susceptor has a circular pocket portion, an annular ledge portion, and an annular rim ledge portion. The circular pocket portion is arranged along a rotation axis and has a perforated surface. The annular ledge portion extends circumferentially about pocket portion and has ledge surface that slopes axially upward from the perforated surface. The rim portion extends circumferentially about the ledge portion and is connected to the pocket portion by the ledge portion of the susceptor. The susceptor has one or more of a tuned pocket, a contact break, a precursor vent, and a purge channel located radially outward of the perforated surface to control deposition of a film onto a substrate supported by the susceptor. Semiconductor processing systems, film deposition methods, and methods of making susceptors are also described.

摘要： A method of forming structure includes providing a substrate in a reaction chamber, forming a first layer overlaying the substrate, and forming a second layer onto the first layer. Temperature of the first layer is controlled during the forming of the first layer using infrared electromagnetic radiation emitted by the first layer. Temperature of the second layer is controlled during the forming of the second layer using infrared electromagnetic radiation emitted by the second layer. Semiconductor device structures and semiconductor processing systems are also described.

摘要： 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.

摘要： A method of depositing one or more epitaxial material layers, a device structure formed using the method and a system for performing the method are disclosed. Exemplary methods include coating a surface of a reaction chamber with a precoat material, processing a number of substrates, and then cleaning the reaction chamber.

摘要： A method of forming a structure is provided. The method includes supporting a substrate within a reaction chamber of a semiconductor processing system, flowing a silicon precursor and a germanium precursor into the reaction chamber, and forming a silicon-germanium layer overlaying the substrate with the silicon containing precursor and the germanium precursor. Concentration of the germanium precursor within the reaction chamber is increased during the forming of the silicon-germanium layer overlaying the substrate. Methods of forming film stack structures, semiconductor device structures, and semiconductor processing systems are also described.

摘要： 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.

摘要： A gas injection system, a reactor system including the gas injection system, and methods of using the gas injection system and reactor system are disclosed. The gas injection system can be used in gas-phase reactor systems to independently monitor and control gas flow rates in a plurality of channels of a gas injection system coupled to a reaction chamber.
