ABSTRACT:
A dielectric-isolated PNP transistor with Schottky protection, either alone or as one of an integrated pair of complementary bipolar transistors has complete dielectric isolation from neighboring devices and from the substrate by means of a topside anisotropic etch. This leaves the devices in mesa form, thinner versions having the facility of lateral terminations, e.g. for the collector. The method is advantageously adapted to provide single type or complementary bipolars with integrated Schottky barrier protection.
