Abstract

A power device includes a substrate, an ion well in the substrate, a body region in the ion well, a source doped region in the body region, a drain doped region in the ion well, and gates on the substrate between the source doped region and the drain doped region. The gates include a first gate adjacent to the source doped region, a second gate adjacent to the drain doped region, and a stacked gate structure between the first gate and the second gate.
