Abstract

PURPOSE:To eliminate the influence to the actuating layer of a depletion layer caused by an interfacial level by providing a semiconductor layer with a lower resistance than the actuating layer on the surface of a semiconductor actuating layer. CONSTITUTION:A buffer layer 2 and an n-type activating layer 3 are grown on a substrate 1 and an n<+>-type layer is grown on the said substrate as a passivation layer 9. Then a source electrode 5, consisting of gold germanium, and a drain electrode 6 are formed on the said passivation layer 9. Next, the passivation layer 9 is selectively removed using a photo resist layer 10 as a mask and a gate metal, consisting of aluminum, is evaporated. Thus the stretch of the depletion layer in the low-resistive passivation crystalline layer, caused by an interfacial level potential, is controlled and its influence is not extended to the actuating layer.
