    摘要: A method is provided for depositing a silicon-containing film in a micro-feature on a substrate by a low pressure deposition process in a processing system. A silicon-containing film can be formed in a micro-feature by providing a substrate in a process chamber of a processing system, and exposing a hexachlorodisilane (HCD) process gas to the substrate. A processing tool containing a processing system for forming a silicon-containing film in a micro-feature using a silicon and chlorine-containing gas such as a HCD process gas is provided. Alternatively, the micro-feature can be exposed to DCS, SiCl4, and SiHCl3 gases. Alternatively, the micro-feature can be exposed to (SiH4+HCl).

    摘要: A method is provided for selectively forming a Si-containing film on a substrate in an interrupted deposition process. The method includes providing a substrate containing a growth surface and a non-growth surface, and selectively forming the Si-containing film on the growth surface by exposing the substrate to HX gas while simultaneously exposing the substrate to a pulse of chlorinated silane gas. The Si-containing film can be a Si film or a SiGe film that is selectively formed on a Si or SiGe growth surface but not on an oxide, nitride, or oxynitride non-growth surface.

    摘要: A method for selectively forming an epitaxial Si containing film on a semiconductor structure at low temperature. The method includes providing the structure in a process chamber, the structure containing a Si substrate having an epitaxial Si surface area and a patterned film area thereon. A Si film is non-selectively deposited onto the structure, the Si film comprising an epitaxial Si film deposited onto the epitaxial Si surface and a non-epitaxial Si film deposited onto an exposed surface of the patterned film. The non-epitaxial Si film is selectively dry etched away to form a patterned epitaxial Si film. The Si film may be a SiGe film.
