Abstract

A semiconductor device with two epitaxial layers formed on a substrate. The middle layer of epitaxial material can be formed thin and with an appropriate doping concentration to provide a low avalanche breakdown voltage with a negative resistance characteristic. The top layer of epitaxial material is doped with the same concentration as the substrate to provide a two-terminal thyristor device with symmetrical bidirectional operating characteristics.
