    摘要: The present invention provides systems and methods of forming an epitaxial film on a substrate. After heating in a process chamber, the substrate is exposed to a silicon source and at least one of SiH2(CH3)2, SiH(CH3)3, Si(CH3)4, 1,3-disilabutane, and C2H2, at a temperature of greater than about 250 degrees Celsius and a pressure greater than about 1 Torr so as to form an epitaxial film on at least a portion of the substrate. Then, the substrate is exposed to an etchant so as to etch the epitaxial film and any other films formed during the deposition. The deposition and etching may be repeated until a film of a desired thickness is achieved. Numerous other aspects are disclosed.

    摘要: In one example, a method of epitaxially forming a silicon-containing material on a substrate surface is presented which includes positioning a substrate into a process chamber. The substrate has a monocrystalline surface and at least a second surface, such as an amorphous surface and/or a polycrystalline surface. The substrate is exposed to a deposition gas to deposit an epitaxial layer on the monocrystalline surface and a polycrystalline layer on the second surface. The deposition gas preferably contains a silicon source and at least a second elemental source, such as a germanium source, a carbon source and/or combinations thereof. Thereafter, the method further provides exposing the substrate to an etchant gas to etch the polycrystalline layer and the epitaxial layer in a manner such that the polycrystalline layer is etched at a faster rate than the epitaxial layer. The method may further include a deposition cycle that includes repeating the exposure of the substrate to the deposition and etchant gases to form a silicon-containing material with a predetermined thickness.
