Double-poly Self-aligned BJT

Double-poly Self-aligned BJT. B-C area small, small C. B-E area small, small C. Extrinsic base regions short and heavily doped, reducing R. Self-alignment allos reduction of area, and reduction of base area. Oxide (SiO 2 ) reduces base and emitter capacitance. Poly increases the ?.
