Semiconductor device and method for production thereof

摘要

The semiconductor device according to the invention includes a substrate, a field insulating region which delimits an active region of the semiconductor substrate, a collector, at least one collector contact region associated with the collector, and a base with an associated base connection region. The collector and the collector contact region are formed in the same active region. In addition the base connection region extends partially over the active region and is separated from the surface of the active region by an insulator layer.
