Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 13:
14. A method of forming a lateral bipolar transistor structure, the method comprising:
forming a semiconductor layer including a first single crystal semiconductor material, the semiconductor layer further including:
an intrinsic base region having a first doping type, and
a first emitter/collector (E/C) region adjacent the intrinsic base region, and having a second doping type opposite the first doping type;
forming a superlattice layer on the first E/C region of the semiconductor layer; and
forming a raised first emitter/collector (E/C) terminal including a second single crystal semiconductor material on the superlattice layer, wherein the superlattice layer separates the first raised E/C terminal from the first E/C region and the intrinsic base region.
