Abstract
In an embodiment, a semiconductor device includes a vertical power FET for switching a load current, the power FET including a channel region of a first conductivity type and a first lateral FET and a second lateral FET providing an output stage of gate driver circuitry for driving the power FET. The first lateral FET includes a channel region of the first conductivity type and the second lateral FET includes a channel region of a second conductivity type opposing the first conductivity type. The power FET and the first and second lateral FETs are monolithically integrated into a semiconductor substrate of the first conductivity type and that has a first surface. A drain of the first lateral FET and a source of the second lateral FET are electrically coupled to a gate of the power FET.
