Abstract:
1. A semiconductor structure comprising: a first semiconductor layer of a first conductivity type, a portion of which is heavily doped; a second semiconductor layer located directly on said first semiconductor layer and having a first doped region of a second conductivity type abutting said heavily doped portion of said first semiconductor layer and a second doped region of said first conductivity type atop said first doping region, wherein said second conductivity type is the opposite of said first conductivity type; and bulk regions and semiconductor-on-insulator regions located directly on said second doped region, wherein said first doped region of said second conductivity type extends from a first of said bulk regions under a first of said semiconductor-on-insulator regions to a second of said bulk regions, said first doped region capacitively coupling a well region of said first bulk region and a well region of said second bulk region.
