Abstract
An embodiment semiconductor device has a first device region disposed on a second device region within an ESD device region disposed within a semiconductor body. Also included is a third device region disposed on the second device region, a fourth device region adjacent to the second device region, a fifth device region disposed within the fourth device region, and a sixth device region adjacent to the fourth device region. The first and fourth regions have a first semiconductor type, and the second, third, fifth and sixth regions have a second conductivity type opposite the first conductivity type. An interface between the fourth device region and the sixth device region forms a diode junction. The first, second, fourth and fifth device regions form a silicon controlled rectifier.
