Disclosed is a semiconductor structure including at least one bipolar junction transistor (BJT), which is uniquely configured so that fabrication of the BJT can be readily integrated with fabrication of complementary metal oxide semiconductor (CMOS) devices on an advanced silicon-on-insulator (SOI) wafer. The BJT has an emitter, a base, and a collector laid out horizontally across an insulator layer and physically separated. Extension regions extend laterally between the emitter and the base and between the base and the collector and are doped to provide junctions between the emitter and the base and between the base and the collector. Gate structures are on the extension regions. The emitter, base, and collector are contacted. Optionally, the gate structures and a substrate below the insulator layer are contacted and can be biased to optimize BJT performance. Optionally, the structure further includes one or more CMOS devices. Also disclosed is a method of forming the structure.

A semiconductor device is described herein. The semiconductor device includes a substrate and a collector region in the substrate. The semiconductor device also includes a plurality of emitter regions in the substrate, each of the plurality emitter regions separate from each other, wherein the plurality of emitter regions is disposed in an area bounded by the collector region.

Disclosed is a semiconductor structure that includes an asymmetric lateral bipolar junction transistor (BJT). The BJT includes an emitter, a base, a collector extension and a collector arranged side-by-side (i.e., laterally) across a semiconductor layer. The emitter, collector and collector extension have a first type conductivity with the collector extension having a lower conductivity level than either the emitter or the collector. The base has a second type conductivity that is different from the first type conductivity. With such a lateral configuration, the BJT can be easily integrated with CMOS devices on advanced SOI technology platforms. With such an asymmetric configuration and, particularly, given the inclusion of the collector extension but not an emitter extension, the BJT can achieve a relatively high collector-emitter breakdown voltage (V.sub.br-CEO) without a significant risk of leakage currents at high voltages. Also disclosed are method embodiments for forming such a semiconductor structure.
