Abstract
A semiconductor device which can prevent peeling off of a gate electrode is provided. The semiconductor device has GaN buffer layerformed on substrate, undoped AlGaN layerformed on this buffer layer, drain electrodeand source electrodeformed separately on undoped AlGaN layer, which form ohmic junctions with undoped AlGaN layer. Between drain electrodeand source electrode, insulating layerwhich has openingis formed, and metal filmis formed on a surface of insulating layer. Gate electrodewhich forms a Schottky barrier junction with undoped AlGaN layeris formed in opening, and gate electrodeadheres to metal film
