Abstract:
According to one embodiment, a semiconductor device includes a semiconductor element and a control device. The semiconductor element includes a first semiconductor region of a first conductivity type, a second semiconductor region of a second conductivity type, a third semiconductor region of the first conductivity type, a conductive portion, and a gate electrode. In a first operation, the control device changes a potential of the conductive portion from a first potential to a second potential. In a second operation, the control device changes a potential of the gate electrode from a third potential to a fourth potential. In a third operation, the control device changes the potential of the gate electrode from the fourth potential to the third potential. In a fourth operation, the control device changes the potential of the conductive portion from the second potential to the first potential after the third operation.
