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 for removing contaminants from an upper surface of a substrate inside various chambers of a semiconductor processing system is provided. The method may comprise heating at least a portion of the upper surface to a predetermined upper surface bake temperature to induce a chemical reaction of the contaminants with hydrogen gas in the deposition chamber and remove contaminants from the upper surface. The temperature of the bulk material forming the substrate remains substantially lower than the predetermined upper surface bake temperature. After heating the upper surface to remove the contaminants, a material layer may be deposited onto the upper surface. The semiconductor processing system and computer instructions for operating the semiconductor processing system are also described.

Abstract: A semiconductor processing system, comprising a chamber configured to support a substrate, a first precursor source, a second precursor source and a dopant source connected to the chamber and a controller operably connected the first precursor source, the second precursor source and the dopant source. The controller responsive to instructions recorded on a memory is to support a substrate within a chamber of a semiconductor processing system, flow a first precursor into the chamber in contact with a first surface of the substrate, form a template layer of silicon-containing film on the first surface of the substrate, etch non-uniformities on the first surface of the substrate, flow a dopant-containing precursor into the chamber in contact with a second surface of the substrate wherein the second surface is a top surface of the template layer, and form a nucleation layer on the second surface.

Abstract: A method of forming a structure includes supporting a substrate within a reaction chamber of a semiconductor processing system, the substrate having a recess with a bottom surface and a sidewall surface extending upwards from the bottom surface of the recess. A film is deposited within the recess and onto the bottom surface and the sidewall surface of the recess, the film having a bottom segment overlaying the bottom surface of the recess and a sidewall segment deposited onto the sidewall surface of the recess. The sidewall segment of the film is removed while at least a portion bottom segment of the film is retained within the recess, the sidewall segment of the film removed from the sidewall surface more rapidly than removing the bottom segment of the film from the bottom surface of the recess. Semiconductor processing systems and structures formed using the method are also described.
