Abstract
Embodiments of the disclosure provide a lateral bipolar transistor structure with a superlattice layer and methods to form the same. The bipolar transistor structure may have a semiconductor layer of a first single crystal semiconductor material over an insulator layer. The semiconductor layer includes an intrinsic base region having a first doping type. An emitter/collector (E/C) region may be adjacent the intrinsic base region and may have a second doping type opposite the first doping type. A superlattice layer is on the E/C region of the semiconductor layer. A raised E/C terminal, including a single crystal semiconductor material, is on the superlattice layer. The superlattice layer separates the E/C region from the raised E/C terminal.
