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 17):
The method of  claim 13 , wherein the method is for fabricating the semiconductor structure further comprising:\n an additional passivation layer disposed directly on the sulfur film layer disposed directly on the sulfur passivated interface surface of the surface layer of indium gallium arsenide, wherein the additional passivation layer comprises at least one material selected from the following: 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 sulfur passivated interface surface of the surface layer of indium gallium arsenide.
