Abstract:
A parasitic capacitance and a leak current in a nitride semiconductor device are reduced. For example, a 100 nm-thick buffer layer made of AlN, a 2 μm-thick undoped GaN layer, and 20 nm-thick undoped AlGaN having an Al composition ratio of 20% are epitaxially grown in this order on, for example, a substrate made of silicon, and a source electrode and a drain electrode are formed so as to be in ohmic contact with the undoped AlGaN layer. Further, in the undoped GaN layer and the undoped AlGaN layer immediately below a gate wire, a high resistance region, the resistance of which is increased by, for example, ion implantation with Ar or the like, is formed, and a boundary between the high resistance region and an element region is positioned immediately below the gate wire.

Claim (Index 10):
The semiconductor device according to  claim 9 , wherein:\n the first and second gate wire layers face each other with the first source electrode and the first drain electrode disposed therebetween in plan view, a plurality of source electrodes each being the first source electrode and a plurality of drain electrodes each being the first drain electrode are provided, and each of the plurality of source electrodes and each of the plurality of drain electrodes are alternately disposed in plan view.
