Abstract:
A semiconductor device according to an embodiment includes a semiconductor layer having a first and a second plane; emitter and collector electrode; a trench gate electrode extending in a first direction substantially parallel to the first plane; a dummy trench gate electrode extending in the first direction; a p base region; an emitter region; an n base region; a collector region; a trench gate insulating film; a dummy trench gate electrode; a dummy trench gate insulating film; a first gate pad electrode connected to the trench gate electrode and the dummy trench gate electrode; a first electric resistor connected between the first gate pad electrode and the trench gate electrode, and a second electric resistor connected between the first gate pad electrode and the dummy trench gate electrode. A CR time constant of the trench gate electrode is less than a CR time constant of the dummy trench gate electrode.
