Abstract

PURPOSE: To reduce the field strength of junction and obtain a high forward blocking voltage by providing a forward voltage carrying junction at the boundary between the diffused layer punching through so as to terminate at the front surface on the anode side and a base layer and making the radius of curvature of the cylindrical diffused layer exposed on the surface equal to the diffusion depth of the punch-through diffused layer.
