Abstract
A semiconductor device comprises a semiconductor layer on an insulator film that is contiguous to a semiconductor substrate. A component, such as a high-voltage diode, forming region is provided in the semiconductor layer and electrically insulated from other component forming regions. A substrate access region is provided in the semiconductor layer and electrically insulated from the component forming region. The substrate access region includes a conductive zone, which extends from the surface down through the semiconductor layer and insulator film to the substrate. A substrate contact is in contact with the conductive zone. The substrate contact and an anode contact of the diode are subject to the same potential.
