A trench MOSFET is disclosed that includes a semiconductor substrate having a vertically oriented trench containing a gate. The trench MOSFET further includes a source, a drain, and a conductive element. The conductive element, like the gate is contained in the trench, and extends between the gate and a bottom of the trench. The conductive element is electrically isolated from the source, the gate, and the drain. When employed in a device such as a DC-DC converter, the trench MOSFET may reduce power losses and electrical and electromagnetic noise.
