Patent ID: 8686493

Claim:
A semiconductor structure including a monolithically integrated trench FET and Schottky diode, the semiconductor structure comprising: a plurality of trenches extending into a semiconductor region of a first conductivity type; a gate electrode in each trench; first and second body regions of a second conductivity type over the semiconductor region between first and second pair of adjacent trenches, respectively; a source region of the first conductivity type over the first body region; a recess extending between each of the first and second adjacent trenches and terminating in the semiconductor region at a depth below the first and second body regions; and an interconnect layer electrically contacting exposed surfaces of the source region and the first and second body regions in each recess, the interconnect layer further contacting the semiconductor region along a bottom of each recess to form a Schottky contact therebetween, the interconnect layer forming an anode terminal of the Schottky diode and a source electrode of the FET.
