Abstract of the Disclosure

The invention is directed to a process for growing an epitaxial film on a single crystal substrate comprising the steps of forming initially an extremely thin film of semiconductor material on a desired substrate or surface by thermal decomposition of a hydride. Subsequently, a thicker film is deposited or grown on the thin film by thermally decomposing a halide in a hydrogen atmosphere or a mixture of halides and hydrides in a hydrogen atmosphere.
