Abstract
An apparatus includes a diode in a layer having a first surface, a second surface opposite the first surface, and a third surface between the first and second surfaces. The diode includes a first region of a first conductivity type at first depth, a second region of a second conductivity type at second depth deeper than the first depth with respect to the second surface, a third region at third depth deeper than the second depth, a fourth region that contacts the third region, a first contact electrode that contacts the second surface and supplies first voltage to the first region, and a second contact electrode that contacts the third surface and supplies second voltage different from the first voltage to the fourth region. The third surface is located between the second region and the second surface.
