    摘要: Semiconductor devices can be fabricated using as an intermediate manufacturing structure a substrate of one semiconductor with a thin epitaxial surface layer of a different semiconductor with properties such that the semiconductors each have different solubilities with respect to a metal. When a vertical differentiation is used to expose the different materials and the metal is deposited on both and heated, the metal will form a Schottky barrier in one material and an ohmic contact in the other. Where the substrate is gallium arsenide and the epitaxial layer is gallium aluminum arsenide and the metal is tin, a self-aligned gallium arsenide MESFET is formed wherein the tin forms ohmic contacts with the gallium arsenide and a Schottky barrier contact with the gallium aluminum arsenide.
