Abstract

PURPOSE:To uniformalize characteristics by a method wherein a Cr added layer or a P type layer is formed in predetermined depth in an N type channel under a gate electrode without etching the surface of an N type operating layer of the GaAs FET, and used as an insulating layer. CONSTITUTION:An N<-> buffer layer 12 and an N layer 13 are formed on an insulating GaAs substrate 11 to which Cr is added in epitaxial shapes. The Cr ion injected layer 17 is made up in prescribed depth, the Al gate electrode 14 is built up on the surface and a Schottky barrier is formed between the N layer 13 and the gate electrode, and ohmic AuGe source electrode 15 and drain electrode 16 are attached at both sides. The FET, characteristics thereof are uniform and which is suitable for changing into an integrated circuit, is obtained because the width W of the channel can be controlled by injecting Cr ions.
