Abstract
A semiconductor substrate has a first doping region arranged at a surface and a second doping region adjacent to the first doping region. A p-n junction between the doping regions is at least partially arranged less than 5 μm away from a contact area of the first doping region arranged at the substrate surface. A first contact structure is in contact with the first doping region in the contact area of the first doping region and has at least partially an electrically conductive material provided for a diffusion into the semiconductor substrate. The first contact structure is configured so that the conductive material provided for a diffusion into the substrate diffuses at least partially through the first doping region into the second doping region in case predefined trigger conditions occur. A second contact structure is in contact with the second doping region in a contact area of the second doping region.
