Abstract
A semiconductor device and a manufacturing method thereof are provided. The semiconductor device includes a substrate, a first well, a second well, and first and second doped regions. The substrate has heavily doped and lightly doped regions. The lightly doped region is disposed over the heavily doped region. The first well is disposed in the lightly doped region. The first well has a conductive type complementary to a conductive type of the heavily doped and lightly doped regions. The second well is disposed in the substrate over the lightly doped region. A location of the first well overlaps a location of the second well. The first and the second doped regions are located in the second well within the active region, and spaced apart from each other. The first and the second doped regions have a same conductive type complementary to a conductive type of the second well.
