Abstract:
A semiconductor device including a Horizontal Current Bipolar Transistor (HCBT) and methods of manufacture. The device has a semiconductor substrate of a first conductivity type defining a wafer plane parallel to the semiconductor substrate and has a base region and a collector region forming a first metallurgical junction. The device also has an emitter region forming a second metallurgical junction with the base region. A flat portion of the first metallurgical junction and a flat portion of the second metallurgical junction are substantially parallel to each other and close an acute angle with the wafer plane. At least a portion of the base region comprises silicon-germanium alloy or silicon-germanium-carbon alloy.
