Abstract:
A semiconductor structure, a method, and an apparatus for in-situ sulfur vapor passivation of an interface surface of an indium gallium arsenide layer of the semiconductor structure. A method includes elemental sulfur-vapor passivation of an interface surface of an indium gallium arsenide layer disposed on a substrate. A dielectric layer can be deposited on the sulfur-vapor passivated interface surface. An annealing process can be performed after the deposition of the dielectric layer. The annealing process anneals the indium gallium arsenide layer including the sulfur-vapor passivated interface surface and the dielectric layer disposed on the sulfur-vapor passivated interface surface. The sulfur-vapor passivation, the deposition of the dielectric layer, and the anneal, can be performed in-situ in a vacuum chamber without breaking a vacuum of the vacuum chamber following a III-V material growth process in the vacuum chamber to form the indium gallium arsenide layer.

Claim (Index 10):
The method of  claim 9 , further comprising:\n heating, by a heating element in the substrate holder, the at least one substrate held by the substrate holder in the work area, to promote sulfurization reaction of thermally-cracked pure sulfur vapor flux deposited onto the exposed interface surface of the indium gallium arsenide layer disposed on each of the at least one substrate held by the substrate holder; and holding in the work area the at least one substrate by the substrate holder being supported by a rotatable platform, and rotating the rotatable platform and thereby rotating the substrate holder and the at least one substrate held in the work area to move the exposed interface surface, of the indium gallium arsenide layer disposed on each of the at least one substrate, across a thermally-cracked pure sulfur vapor flux output field emitted from the output end of the sulfur vapor thermally cracking zone channel, to uniformly distribute the highly reactive thermally-cracked pure sulfur vapor flux from the output directly onto the exposed interface surface of the indium gallium arsenide layer disposed on each of the at least one substrate held by the substrate holder.
