Patent ID: 8592904

Claim:
A semiconductor device comprising: a semiconductor chip including a schottky barrier diode and a plurality of power MOSFETs which are formed on a single semiconductor substrate; the semiconductor substrate having a first long side, a second long side located on the opposite side of the first long side, a first short side and a second short side located on the opposite side of the first short side; the schottky barrier diode formed in a first region of the semiconductor substrate; and the plurality of power MOSFETs formed in a second region of the semiconductor substrate, wherein the first region is closer to the first short side than a central portion of the semiconductor substrate and is arranged between the first short side and the second region, wherein the second region is arranged between the first region and the second short side, wherein each of the power MOSFETs has a gate electrode, a drain region and a source region, wherein each of the gate electrodes is embedded in a trench formed in the semiconductor substrate, wherein a first pad is formed over the power MOSFETs and the schottky barrier diode, and is electrically connected to the source region and the schottky barrier diode, and wherein a gate wiring is electrically connected to the gate electrode and surrounds the first pad in a planar view; and wherein the schottky barrier diode is surrounded at four sides by the gate wiring in a planar view.
