摘要:
A nitride semiconductor device includes a substrate, a first Inx1Ga1-x1-y1Aly1N layer, a second Inx2Ga1-x2-y2Aly2N layer, an interlayer insulating film, a source electrode, a drain electrode, a first gate electrode, a Schottky electrode, a second gate electrode, an interconnection layer. The second Inx2Ga1-x2-y2Aly2N layer is provided on a surface of the first Inx1Ga1-x1-y1Aly1N layer. The second Inx2Ga1-x2-y2Aly2N layer has a wider band gap than the first Inx1Ga1-x1-y1Aly1N layer. The first gate electrode is provided between the source electrode and the drain electrode on a surface of the second Inx2Ga1-x2-y2Aly2N layer. The Schottky electrode is provided on the second Inx2Ga1-x2-y2Aly2N layer between the first gate electrode and the drain electrode. The second gate electrode is provided on the second Inx2Ga1-x2-y2Aly2N layer between the Schottky electrode and the drain electrode. The interconnection layer electrically connects the source electrode, the Schottky electrode, and the second gate electrode.
