ABSTRACT:
A semiconductor controlled rectifier, having a semiconductor body with at ast four zones of alternatingly opposite conductivity types, includes a highly doped outer emitter zone of a first conductivity type and a bordering weakly doped inner zone of an opposite conductivity type. The outer emitter zone is formed so as to have a plurality of sections. Portions of the inner zone extend up to the level of the outer surface of the emitter zone between the sections of the emitter zone. These portions of the inner zone are interconnected and bar shaped. The inner zone, therefore, forms a contiguous geometric pattern on the outer surface. A conductive coating is placed on the outer surface and serves as a contact electrode for the rectifier.
