Abstract

PURPOSE:To raise surge voltage resistance in the reverse direction by a method wherein on the surface of an n<-> epitaxial layer held between an n<+> cathode layer and a p<+> separating layer is provided an n<+> layer in specified width which is separated at distances x2 and x1 from both cathode and separating layers respectively and surrounds the cathode layer and the distance x1 is made smaller than the thickness of the epitaxial layer directly under the cathode layer. CONSTITUTION:When the surge voltage in the reverse direction is applied to the anode 6 (p<+> separating layer 4) and the cathode (N<+> layer 3), it makes punch- through between the layers 8 and 4, a current flowing along the surface of the epitaxial layer 2 flows inside of the epitaxial layer 2 between the layers 8 and 3, and the resistance thereof restricts the punch-through current and increase voltage breaking strength. The dimension x2 is made large, (w) is made small and the resistance of the n<+> layer 8 along the direction (y) is made large, thereby the expansion of the punch-through current in the direction (y) being prevented and current restricting resistance being increased. In the case when forward voltage is applied between the electrodes 6 and 7, the surface resistance of the epitaxial layer 2 is increased due to the restricting resistance, but the drop of voltage is not increased since the current flows mainly from the n<+> layer 3 to a p type substrate 1 just under the layer 3.
