Abstract
According to one embodiment, a semiconductor device includes a first semiconductor region, a second semiconductor region, a third semiconductor region, a first electrode, a second electrode, a control electrode and an insulating film. The first semiconductor region is of a first conductivity type and includes SiC. The second semiconductor region is provided on the first semiconductor region and has a first surface. The second semiconductor region is of a second conductivity type and includes SiC. The third semiconductor region is provided on the second semiconductor region, is of the first conductivity type and includes SiC. The first and second electrodes are electrically connected to the third semiconductor region. The control electrode is provided on the second semiconductor region. The insulating film is provided between the second semiconductor region and the control electrode. The insulating film contacts the first surface and the control electrode and includes nitrogen.
