IPC: H02H7/20
Filed: 1980-08-11
Abstract: PURPOSE:To lower the reverse voltage resisting capability of a protective diode by a method wherein impurity concentration is kept low in a substrate surface. CONSTITUTION:A highly doped P type semiconductor substrate 1 is covered with an epitaxially grown single crystal semiconductor layer 2 that possesses the same type of conductivity as the substrate 1 but is sufficiently lower as regards impurity  concentration than in the substrate 1. The surface of the single crystal semiconductor layer 2 is then subjected to such a heat treatment process as ion injection or diffusion which results in the formation of a semiconductor domain 3 conductive feature whereof is different from the substrate 1 thanks to the introduction of highly  concentrated impurities with a different conductive feature. The domain 3 extends  to the highly doped substrate 1. The domain 3 thus has two junctions: a P-N type junction wherein the bottom of the domain 3 meets the substrate 1 at a junction 4 and the other wherein the side of the domain 3 meets the semiconductor 2 at a  junction 5.
