    摘要: Methods for removing residue from interior surfaces of process chambers are provided herein. In some embodiments, a method of conditioning interior surfaces of a process chamber may include maintaining a process chamber at a first pressure and at a first temperature of less than about 800 degrees Celsius; providing a process gas to the process chamber at the first pressure and the first temperature, wherein the process gas comprises chlorine and nitrogen to remove residue disposed on interior surfaces of the process chamber; and increasing the pressure in the process chamber from the first pressure to a second pressure while continuing to provide the process gas to the process chamber.

    摘要: Methods of preparing a clean surface of germanium tin or silicon germanium tin layers for subsequent deposition are provided. An overlayer of Ge, doped Ge, another GeSn or SiGeSn layer, a doped GeSn or SiGeSn layer, an insulator, or a metal can be deposited on a prepared GeSn or SiGeSn layer by positioning a substrate with an exposed germanium tin or silicon germanium tin layer in a processing chamber, heating the processing chamber and flowing a halide gas into the processing chamber to etch the surface of the substrate using either thermal or plasma assisted etching followed by depositing an overlayer on the substantially oxide free and contaminant free surface. Methods can also include the placement and etching of a sacrificial layer, a thermal clean using rapid thermal annealing, or a process in a plasma of nitrogen trifluoride and ammonia gas.

    摘要: A method and apparatus for forming semiconductive semiconductor-metal alloy layers is described. A germanium precursor and a metal precursor are provided to a chamber, and an epitaxial layer of germanium-metal alloy, optionally including silicon, is formed on the substrate. The metal precursor is typically a metal halide, which may be provided by evaporating a liquid metal halide, subliming a solid metal halide, or by contacting a pure metal with a halogen gas. A group IV halide deposition control agent is used to provide selective deposition on semiconductive regions of the substrate relative to dielectric regions. The semiconductive semiconductor-metal alloy layers may be doped, for example with boron, phosphorus, and/or arsenic. The precursors may be provided through a showerhead or through a side entry point, and an exhaust system coupled to the chamber may be separately heated to manage condensation of exhaust components.
