Abstract
Provided is a semiconductor device that includes: a semiconductor substrate having a first doped region of a first doping type and a second doped region of a second doping type, the first doped region being beneath but immediately adjacent to, the second doped region, with the first doping type being opposite the second doping type, thereby forming a junction region between the first doped region and the second doped region; and an additional layer that has been deposited above the junction region having similar mechanical properties as the semiconductor substrate. The additional layer covers at least 50% of a projection area of the junction region. The second doped region has a top surface, the additional layer has a bottom surface, and at least 90% of the bottom surface of the additional layer is electrically insulated from the top surface of the second doped region.
