Abstract
A bipolar transistor, comprising a collector region, a base region, and an emitter region, is a type which is compatible to CMOS processes leading to the formation, on a semiconductor substrate, of N-channel and P-channel MOS transistors having respective source and drain regions. In such bipolar transistor, the collector region is a substrate diffused pocket and the base region is formed within the diffused pocket simultaneously with the source and drain regions of the P-channel MOS transistors. Further, the emitter region is incorporated, in turn, to the base region simultaneously with the source and drain regions of the N-channel MOS transistors.
