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 4):
The method of  claim 1 , wherein the annealing includes annealing the semiconductor structure in hydrogen gas containing ambient at temperature greater than 300\u00b0 C. to obtain an interface defect density (D it ) distribution at the sulfur-vapor passivated interface surface of the indium gallium arsenide layer to less than 2\u00d710 11  eV \u22121  cm \u22122  measured near mid gap across a band-gap.
