Abstract
A semiconductor device is provided having a first semiconductor region comprising an n-type semiconductor and a second semiconductor region of an n-type semiconductor having a higher resistivity than the first semiconductor region. An insulation film is provided adjacent to the semiconductor region having an aperture therein, and an electrode region is provided in the aperture. A third semiconductor region comprising a p-type semiconductor is provided at a junction between the insulation film and the electrode region. The electrode comprises a monocrystalline metal and constitutes a Schottky junction with the semiconductor region. An ohmic electrode comprising aluminum is arranged on the electrode region.
