发明名称 Ion implantation and process sequence to form smaller base pick-up
摘要 Methods for forming a bipolar junction transistor device are described herein. A method for forming the bipolar junction transistor device may include doping a first portion of a substrate with a first dopant to form a base pick-up region, and after doping the first portion of the substrate, doping a second portion of the substrate with a second dopant to form at least one emitter region. A bipolar junction transistor device may include a floating collector, in which case the bipolar junction transistor device may be operated as a diode for improved emitter current.
