Abstract
According to one embodiment, a semiconductor device includes first, second, and third semiconductor regions, first, second, and third electrodes, and a first insulating portion. The first semiconductor region includes first and second partial regions. A first direction from the second partial region toward the second semiconductor region crosses a second direction from the second region toward the first partial region. The third semiconductor region is provided between the second partial region and the second semiconductor region in the first direction. The first insulating portion includes a first insulating region provided between the third semiconductor region and the first electrode in the second direction, a second insulating region provided between the first partial region and the first electrode in the first direction, and a third insulating region provided between the first partial region and the first insulating region in the first direction.
