Abstract:
1. A semiconductor device comprising: a first layer including a group-III nitride semiconductor of a first conduction type; a second layer including a group-III nitride semiconductor of a second conduction type on a first surface of the first layer; a third layer including an Al-containing group-III nitride semiconductor on a first region of a surface of the second layer; a gate electrode having one end above a surface of the third layer and the other end within the first layer via the second layer, the gate electrode being insulated from the first layer, the second layer and the third layer; a first electrode connected to the third layer; a second electrode connected to a second region of the surface of the second layer; and a third electrode provided above a second surface of the first layer, the second surface being opposite to the first surface of the first layer.
