Abstract of the Disclosure

The epitaxial growth of semiconductor layers is confined to selected areas with the use of an oxide mask. The simultaneous growth of polycrystalline semiconductor material on the oxide mask is prevented by the continuous addition of a small amount of hydrogen halide to the gaseous mixture passed through the epitaxial reactor.
