Abstract

Modern bipolar integrated circuits have demand- ing junction profile requirements. Device designs that have 0.3 pm base-collector junction depths and 0.1 micron emitter-base junction depths require careful control of thermal cycles during processing. For the emitter anneal application, a novel diffusion canti- lever system has been designed that maintains shal- low junctions with sharp junction interface profiles.
