Abstract
A method of manufacturing an integrated circuit includes forming first and second false collector regions of a first conductivity type adjacent to a surface of an epitaxial layer of semiconductor material. The first false collector region is located laterally on a first side of a base region. The base region is formed within the epitaxial layer and has a second conductivity type. The second false collector region is located laterally on a second side of the base region. The second side is opposite the first side of the base region. The base region is a base of a parasitic bipolar junction in an isolation region of an active semiconductor device.
