Abstract

A device includes a vertical transistor comprising a first gate in a first trench, wherein the first gate comprises a dielectric layer and a gate region over the dielectric layer, and a second gate in a second trench, a high voltage lateral transistor immediately adjacent to the vertical transistor and a low voltage lateral transistor, wherein the high voltage lateral transistor is between the vertical transistor and the low voltage lateral transistor.
