Abstract
A bipolar transistor is provided in which the base-emitter junctions do not traverse the base but terminate inside the top surface of the base. The transistor has long emitter perimeter available for current flow and more than two emitter sides (e.g., three sides) available for current flow, which allows obtaining a low base resistance, a low emitter resistance, a low collector resistance, a low base-collector capacitance, and a small size.
