发明名称 System and method for gas-phase sulfur passivation of a semiconductor surface
摘要 Improved methods and systems for passivating a surface of a high-mobility semiconductor and structures and devices formed using the methods are disclosed. The method includes providing a high-mobility semiconductor surface to a chamber of a reactor and exposing the high-mobility semiconductor surface to a gas-phase sulfur precursor to passivate the high-mobility semiconductor surface.

主权项 1. A method of passivating a surface of a semiconductor, the method comprising the steps of: providing the surface of the semiconductor to a reaction chamber of a reactor; exposing the surface of the semiconductor to a gas-phase sulfur precursor selected from the group consisting of H2S, NH4HS, and organosulfur compounds in the reaction chamber; and passivating the surface of the semiconductor in the reaction chamber using the gas-phase sulfur precursor to form a passivated semiconductor surface, wherein a pressure within the reaction chamber during the step of passivating is between 0.5 Torr and 750 Torr.
