Abstract: A semiconductor device may include a semiconductor substrate, a first conductive type well and a second conductive type drift region in the semiconductor substrate, the drift region including a first drift doping region and a second drift doping region, the second drift doping region vertically overlapping the well, and a first conductive type body region in the well, the body region being in contact with a side of the first drift doping region. The first drift doping region and the second doping region may include a first conductive type dopant and a second conductive type dopant, and an average density of the first conductive type dopant in the first drift doping region may be less than an average density of the first conductive type dopant in the second drift doping region.
