Abstract:
Fabrication methods, device structures, and design structures for a bipolar junction transistor. An emitter is formed in a device region defined in a substrate. An intrinsic base is formed on the emitter. A collector is formed that is separated from the emitter by the intrinsic base. The collector includes a semiconductor material having an electronic bandgap greater than an electronic bandgap of a semiconductor material of the device region.
