Abstract

A metal-semiconductor field-effect transistor is formed by providing a blanket layer of the same conductivity type as the semiconductor body, with field oxide subsequently being grown, and with a region of opposite conductivity type being formed to extend partially under the field oxide, the initial blanket layer acting as the field implant region of the field-effect transistor.
