Abstract
Embodiments of the disclosure provide a bipolar transistor structure including a semiconductor fin on a substrate. The semiconductor fin has a first doping type, a length in a first direction, and a width in a second direction perpendicular to the first direction. A first emitter/collector (E/C) material is adjacent a first sidewall of the semiconductor fin along the width of the semiconductor fin. The first E/C material has a second doping type opposite the first doping type. A second E/C material is adjacent a second sidewall of the semiconductor fin along the width of the semiconductor fin. The second E/C material has the second doping type. A width of the first E/C material is different from a width of the second E/C material.
