Abstract: PURPOSE:To obtain a compound semiconductor device having a gate electrode, which indicates excellent Schottky characteristics, by using a metal, which has excellent adhesion with an insulating material, as a second metal layer laminated on a first metal layer, which is provided so as to constitute a Schottky junction together with a substrate. CONSTITUTION:An electrode 18 has a structure, in which a second metal layer 14 indicating excellent adhesion with an insulating material is laminated on a first metal layer 13 that forms a Schottky junction together with a substrate.

The second metal layer 14 comprising Ti is closely attached to the insulating film comprising SiO2 and the like. The electrode 18 comprises the Ti layer 14 and the WNn layer 13. Since the junction part with the compound semiconductor substrate comprises a conductive material, which includes at least the heat resisting metal and nitrogen, the barrier height against the substrate is high, and heat resistance becomes good even during heat treatment. Thus, the electrode 18, which has the excellent Schottky characteristics even after the heat treatment, is obtained.
