A heterojunction field-effect semiconductor device has a main semiconductor region comprising two layers of dissimilar materials such that a two-dimensional electron gas layer is generated along the heterojunction between the two layers. A source and a drain electrode are placed in spaced positions on a major surface of the main semiconductor region and electrically coupled to the 2DEG layer. Between these electrodes, a gate electrode is received in a recess in the major surface of the main semiconductor region via a p-type metal oxide semiconductor film and insulating film, whereby a depletion zone is normally created in the 2DEG layer, making the device normally off. The p-type metal oxide semiconductor film of high hole concentration serves for the normally-off performance of the device with low gate leak current, and the insulating film for further reduction of gate leak current.
