Abstract
A semiconductor device structure includes a substrate having a background doping of a first concentration and of a first conductivity type. A through substrate via (TSV) is through the substrate. A device has a first doped region of a second conductivity on a first side of the substrate. A second doped region is around the TSV. The second doped region has a doping of a second concentration greater than the first concentration and is of the first conductivity type.
