Abstract

A power semiconductor structure (200), in particular in VIPower technology, made from a chip of N-type semiconductor material (110), comprising a bipolar or field-effect vertical power transistor (125, 120, 110) having a collector or drain region in such N-type material (110); the semiconductor structure comprises a PNP bipolar lateral power transistor (210, 110, 220) having a base region in such N-type material (110) substantially in common with the collector or drain region of the vertical power transistor.
