Abstract
In a high voltage integrated circuit, a low voltage region is separated from a high voltage region by a junction termination. A bipolar transistor in the high voltage region is surrounded by an isolation region having a low doping concentration. The use of a low-doped isolation region increases the size of an active region without reduction of a breakdown voltage.
