Abstract
According to one embodiment, a semiconductor device includes first and second electrodes, first to third semiconductor regions, first and second conductive parts, first and second gate electrodes, and a first connection part. The first semiconductor region is located on the first electrode. The second semiconductor region is located on the first semiconductor region. The third semiconductor region is located on a portion of the second semiconductor region. The first conductive part is located in the first semiconductor region with a first insulating part interposed. The first gate electrode is located in the first insulating part. The second conductive part is located in the first semiconductor region with a second insulating part interposed. The second gate electrode is located in the second insulating part. The first connection part is located higher than the second and third semiconductor regions. The second electrode is located on the second and third semiconductor regions.
