Abstract : The present invention relates, in general, to a process for depositing III-V semiconducter compounds as epitaxial films onto semiconductor substrates which are crystallographicaly compatible with said films. In a more particular aspect, this invention relates to a process for effecting a continuous, insitu, hydrogen chloride etch during the vapor phase epitaxial deposition of III-V mixed compounds onto semiconductor compounds. The resulting epitaxial structures find particular utility in the fabrication of double heterostructure lasers, light-emitting diodes and field effect transistors. III-V semiconductor compounds, as is well understood by those skilled in semiconductor technology, are those which include elements from group III and group V of the Periodic Table of Elements. The components can be binary, ternary, or quaternary mixtures of any of those elements.
