Abstract
A process of forming an epitaxial metal silicide layer on a silicon substrate is disclosed. A thin layer of a first metal that will form an oxide in preference to silicon is initially deposited on the substrate. A preferred first metal is titanium. A layer of palladium, platinum or iridium is deposited thereover. An exceptionally uniform, conductive layer of metal silicide is thereby formed by epitaxial growth without the necessity of a high temperature anneal. The disclosed process is particularly useful in forming ultra thin metal silicide Schottky barriers in devices such as infrared imaging arrays.
