Abstract:
A semiconductor component comprising:a substrate;an electrode located over the substrate and having a first side and a second side opposite the first side;a first doped region located in the substrate, self-aligned to the first side of the electrode, and having a first doping concentration;a second doped region located in the substrate at the second side of the electrode and having the first doping concentration;a third doped region located in the substrate at the second side of the electrode between the first and second doped regions and having a second doping concentration less than the first doping concentration; anda fourth doped region located in the substrate at the second side of the electrode between the second and third doped regions and having a third doping concentration different from the second doping concentration and less than the first doping concentration;wherein a first distance between an edge of the third doped region and an edge of the fourth doped region is different from a second distance between the edge of the fourth doped region and an edge of the second doped region.
