Abstract

Conduction between source and drain or emitter and collector regions is an important characteristic in transistor operation, particularly for lateral bipolar transistors. Accordingly, techniques that can facilitate control over this characteristic can mitigate yield loss by promoting the production of transistors that have an increased likelihood of exhibiting desired operational performance. As disclosed herein, well regions are established in a semiconductor substrate to facilitate, among other things, control over the conduction between the source and drain regions of a lateral bipolar transistor, thus mitigating yield loss and other associated fabrication deficiencies. Importantly, an additional mask is not required in establishing the well regions, thus further mitigating (increased) costs associated with promoting desired device performance.
