Abstract of the Disclosure

An improved high voltage Schottky barrier diode includes a semiconductor layer having two adjacent sublayers of the same type conductivity but different doping concentrations. A plurality of isolated discrete regions of a second type conductivity opposite to that of the first are provided along the boundary region between the sublayers and beneath the Schottky junction. The invention results in an improved high voltage Schottky diode in which the reverse characteristics are substantially enhanced
