Abstract
A monolithically integrated trench FET and Schottky diode includes a plurality of trenches extending into a FET region and a Schottky region of a semiconductor layer. A trench in the Schottky region includes a dielectric layer lining the trench sidewalls, and a conductive electrode having a top surface that is substantially coplanar with a top surface of the semiconductor layer adjacent the trench. An interconnect layer electrically contacts the semiconductor layer in the Schottky region so as to form a Schottky contact with the semiconductor layer.
