Abstract: A method of forming silicon within a gap on a surface of a substrate. The method includes use of two or more pyrometers to measure temperatures at two or more positions on a substrate and/or a substrate support and a plurality of heaters that can be divided into zones of heaters, wherein the heaters or zones of heaters can be independently controlled based on the measured temperatures and desired temperature profiles.

Abstract: A chamber arrangement includes a chamber body, a substrate support, and an upper heater element array. The chamber body has injection and longitudinally opposite exhaust ends, the substrate support is arranged within the chamber body and supported therein for rotation about a rotation axis, and the upper heater element array is supported above the chamber body and include a laterally-inner first upper linear lamp and a laterally-inner second upper linear lamp. The laterally-inner first upper linear lamp is separated from the rotation axis by a first lateral spacing distance, the laterally-inner second upper linear lamp is separated from the rotation axis by a second lateral spacing distance, and one of the first lateral spacing distance and the second lateral spacing distance is greater than the other of the first lateral spacing distance the second lateral spacing distance. Semiconductor processing systems and material layer deposition methods are also described.

Abstract: 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.

Abstract: 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.
