ABSTRACT:
A body of semiconductor material has opposed end surfaces, opposed side surfaces extending to the end surfaces and opposed first and second contact surfaces which are substantially perpendicular to the end and side surfaces. The body includes a substrate having on a surface thereof a mesa shaped active region which extends to the first contact surface. The active region has side surfaces which are spaced from the side surfaces of the body. Also on the substrate are passive regions which extend from the side surfaces of the active region to the first contact surface and side surfaces of the body. The active region has a P-N junction therein. The passive regions each include a plurality of contiguous passive layers having, P-N junctions therebetween. The P-N junctions of the passive regions extend from the first contact surface to the side surface of the body. Metallic electrodes are on each of the contact surfaces. The passive regions serve to restrict current flow to the active region.
