Patent ID: 7701038

Claim:
A lateral bipolar junction transistor comprising: a well region of a first conductivity type formed over a substrate; an emitter in the well region, wherein the emitter is a doped region formed of a second conductivity type opposite the first conductivity type, and wherein the emitter has a polygon shape with a plurality of sides; a plurality of collectors of the second conductivity type, each of the collectors being disposed as a separate doped region formed in the well region, the plurality of collectors being electrically interconnected to each other, wherein each one of the plurality of sides of the emitter has one of the plurality of collectors adjacent and substantially aligned with one of the collectors, each of the doped regions forming the collectors being separated from each other by the well region; a plurality of base contacts of the first conductivity type formed as doped regions in the well region and electrically interconnected to each other, wherein each of the base contacts are adjacent one or more of the collectors, and wherein none of the base contacts are adjacent or substantially aligned with a side of the emitter; and wherein the well region is interposed between the doped region forming the emitter and neighboring doped regions forming collectors and the well region is interposed between the doped region forming the emitter and neighboring doped regions forming base contacts.
