Abstract:
A semiconductor component arranged at a surface of a substrate, the semiconductor component comprising an active part and a plurality of contact plugs of a material having a good electrical conductivity, the contact plugs arranged in at least one row positioned at a perimeter of the active part and the contact plugs extending from the surface of the semiconductor component into the substrate and having top regions located at the surface of the semiconductor component and bottom regions that terminate at an inner region of the substrate, the contact plugs being in electrical contact with the substrate at least in said bottom regions, wherein the bottom regions of the contact plugs comprise electrical contact enhancing means that comprise at least one of an additional diffusion and doping layer, thereby forming an electrical interconnection between the inner region of the substrate and the surface, for shielding the active part of the semiconductor component from electrical fields and electrical currents in the substrate.
