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 8):
The method of  claim 7 , wherein the additional passivation layer disposed directly on the thermally-cracked elemental sulfur vapor passivated interface surface comprises at least one material selected from the following:\n ammonium sulfide ((NH 4 ) 2 S), hydrogenated amorphous silicon (a-Si:H), gallium gadolinium oxide ((Ga 2 O 3 ) 1-x (Gd 2 O 3 ) x , or GGO), zinc sulfide (ZnS), and cadmium sulfide (CdS), to further passivate the thermally-cracked sulfur vapor passivated interface surface of the indium gallium arsenide layer disposed on the substrate.
