Abstract:
A GaN-based semiconductor device comprising:a III-V nitride semiconductor layer having a predetermined width; a first anode electrode forming a Schottky junction with said III-V nitride semiconductor layer, with a junction width narrower than the predetermined width of said III-V nitride semiconductor layer; and a second anode electrode forming a Schottky junction with a portion of said III-V nitride semiconductor layer other than a portion at which said first anode electrode is in contact with said III-V nitride semiconductor layer, said second anode electrode being electrically connected with said first anode electrode, a Schottky barrier formed between said first anode electrode and said III-V nitride semiconductor layer being lower in height than that formed between said second anode electrode and said III-V nitride semiconductor layer.
