Abstract
An integrated circuit (IC) includes a high-voltage (HV) MOSFET on a substrate. The substrate includes a handle substrate region, an insulating region, and a silicon region. Source region and drain regions, which have a first conductivity type, are disposed in the silicon region and spaced apart from one another. A gate electrode is disposed over an upper region of the silicon region and is arranged between the source and drain regions. A body region, which has a second conductivity type, is arranged under the gate electrode and separates the source and drain regions. A lateral drain extension region, which has the first conductivity type, is disposed in the upper region of the silicon region and extends laterally between the body and drain regions. A breakdown voltage enhancing region, which has the second conductivity type, is disposed in the silicon region under the lateral drain extension region.
