ABSTRACT:
A semiconductor protection circuit comprises a semiconductor substrate of a first conductivity type; a first region of the first conductivity type formed in the substrate at a surface thereof and having a relatively different degree of conductivity from the substrate; a region of a second conductivity type formed in the first region of the first conductivity type; and a second region of the first conductivity type formed partly in each of the semiconductor substrate and the first region of the first conductivity type so as to bridge a junction therebetween.
