Abstract
A diode structure is disclosed wherein the diode includes a body of a first type conductivity material; a first region of a second conductivity material in the body and having an opening therein through which a portion of the body projects; and a second region of the first conductivity material in the portion of the body that projects through the opening. The second region is rotationally positioned with respect to the first region so that it partially overlaps the first region at points of intersection of the two regions. These points of intersection are the rectifying junctions. The respective shapes of the opening and of the second region are arranged so that the sum of the areas of the breakdown junctions is a constant value notwithstanding that the second region may be displaced or misaligned with respect to the first region, provided that relative displacement or misalignment of the two regions is within defined limits.
