Abstract
A semiconductor device includes first and second electrodes, first to fourth semiconductor regions, first and second control electrodes, and first and second electrode pads. 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 the second semiconductor region. The fourth semiconductor region is located on a portion of the third semiconductor region. The first control electrode faces the second, third, and fourth semiconductor regions via a first insulating film. The second control electrode faces the second and third semiconductor regions via a second insulating film. The first electrode pad is electrically connected with the first control electrode. The second electrode pad is electrically connected with the second control electrode. The second electrode pad has a different planar shape from the first electrode pad.
