Abstract
A semiconductor device includes a substrate, a gate positioned on the substrate, a drain and a source formed in the substrate at respective two sides of the gate, and a doped region formed in the source. The drain and the source comprise a first conductivity type and the doped region comprises a second conductivity type. The first conductivity type and the second conductivity type are complementary to each other.
