Abstract:
Semiconductor devices each include: a semiconductor substrate that contains beta-gallium oxide and has a first conductivity type; a first semiconductor region that contains beta-gallium oxide, has the first conductivity type, and is provided on an upper side of the semiconductor substrate; a second semiconductor region that contains beta-gallium oxide, has a second conductivity type, and is provided on an upper side of a part of the first semiconductor region; and a third semiconductor region that contains beta-gallium oxide, has the first conductivity type, and is provided on an upper side of a part of the second semiconductor region. When the first conductivity type is an n-type and the second conductivity type is a p-type, the second semiconductor region further contains a band gap control element. The band gap control element is selected from a group of boron, aluminum, and indium.
