Abstract
Embodiments of the disclosure provide a lateral bipolar transistor structure with inner and outer spacers, and related methods. A lateral bipolar transistor structure may have an emitter/collector (E/C) layer over an insulator. The E/C layer has a first doping type. A first base layer is on the insulator and adjacent the E/C layer. The first base layer has a second doping type opposite the first doping type. A second base layer is on the first base layer and having the second doping type. A dopant concentration of the second base layer is greater than a dopant concentration of the first base layer. An inner spacer is on the E/C layer and adjacent the second base layer. An outer spacer is on the E/C layer and adjacent the inner spacer.
