Abstract

The invention relates to a high-breakdown voltage heterostructure field-effect transistor (FET), which can be used under a high temperature condition. The FET device from bottom upward in succession includes a semiconductor substrate, a buffer layer, a delta-doped sheet, an undoped layer, a sub-channel layer, an active channel layer, a gate layer, and an ohmic contact layer.
