METHOD AND APPARATUS FOR ATOMIC HYDROGEN SURFACE TREATMENT DURING GaN EPITAXY

摘要

Methods and apparatus for generating and delivering atomic hydrogen to the growth front during the deposition of a III-V film are provided. The apparatus adapts HWCVD technology to a system wherein the Group III precursor and the Group V precursor are delivered to the surface in isolated processing environments within the system. Multiple HWCVD units may be incorporated so that the atomic hydrogen parameters may be varied in a combinatorial manner for the development of III-V films.
