Abstract

A compound semiconductor field effect transistor having, between a gate electrode and a drain electrode, a non-gate region which is the channel region not covered by the gate electrode, wherein a plurality of isolation regions are formed in the non-gate region in such a way that they extend in the direction of channel current and contact with the gate electrode. This compound semiconductor field effect transistor is improved in breakdown voltage between drain and gate and yet retains the high-speed operability of transistor.
