Abstract:
A lateral PNP bipolar electronic device integrated monolithically on a semiconductor substrate together with other bipolar devices of the NPN type, said device comprising:the semiconductor substrate, doped with impurities of the P-type;a first buried layer in the semiconductor substrate, the first buried layer being doped with impurities of the N-type to provide a base region, being delimited on opposite sides by a pair of insulation regions, and having a sinker region that extends to a surface of the semiconductor substrate;a second layer, overlying the first buried layer and having conductivity of the N-type, to provide an active area, wherein within said active area, a P-doped emitter region is located along a periphery of the active area at an opposite location from a P-doped collector region;a base region formed in the sinker region of the first buried layer, the collector region being located between the emitter and base regions; andan emitter contact electrically coupled to the emitter region and positioned completely on an opposite side of one of the insulation regions from the emitter region.
