  • Method of fabricating a Schottky gate field effect transistor
    Patent number: 4472872
    Abstract: A Schottky gate FET is fabricated by forming on a semiconductor substrate first and second stacks facing each other. Each stack is constructed by an ohmic electrode and a spacer film. On the substrate having stacks formed thereon an insulation layer is formed and is anisotropically etched in the direction of its thickness until the planar surface portions are exposed. As a result, portions of the insulation layer remain on opposing side walls of the stacks. After removing the spacer films to define stepped portions between each remaining portion and each electrode, a layer of a metallic material capable of forming a Schottky barrier with the substrate is formed. The remaining portions are removed to pattern the metallic material layer, thereby forming a Shottky gate electrode.
