Abstract:
1. A semiconductor device, comprising: a substrate comprising a first major surface at a front side and a second major surface at a back-side opposite the front side; a first device comprising a first semiconductor material region and disposed in the substrate at the front side; a second device comprising a second semiconductor material region and disposed in the substrate laterally adjacent the first device; a recombination zone comprising a third semiconductor material region and disposed in the substrate, the third semiconductor material region being a different material than the first semiconductor material region and the second semiconductor material region, the recombination zone extending in to the substrate from the first major surface of the substrate, the recombination zone being disposed between the first device and the second device; and a back-side recombination layer comprising a fourth semiconductor material region and disposed at the second major surface of the substrate.
