Abstract
A semiconductor device includes a first electrode, a first semiconductor region, a second semiconductor region, a third semiconductor region, a second electrode, a conductive part, and a fourth semiconductor region. The first semiconductor region is located above the first electrode. The second semiconductor region is located on the first semiconductor region. The third semiconductor region is located on the second semiconductor region. The second electrode is located on the second and third semiconductor regions. The second electrode is electrically connected with the second and third semiconductor regions. The conductive part includes a first conductive region and a second conductive region. The first conductive region faces the first to third semiconductor regions via an insulating film. The second conductive region is located around the second electrode. The fourth semiconductor region is located around the second semiconductor region. The fourth semiconductor region is electrically connected with the second semiconductor region.
