摘要：
A method has been proposed to improve the lateral PNP (LPNP) in semiconductor devices by forming small PNP emitters by image transfer from a sidewall. The narrow width of the smaller emitter and self-aligned contact reduces series emitter resistance. Beta characteristics also are significantly improved. The invention calls for changes in a conventional bipolar manufacturing process following a 450 OMEGA /square resistor implant step as outlined.
