Abstract

A normally-off field effect transistor having the structure of an IGFET with a substantially undoped semiconductor material replacing the insulation between the substrate and the gate metal. A Schottky barrier formed between the gate metal and the substantially undoped semiconductor material produces a channel in the substrate when reverse biased. Method of fabrication is also described.
