Claim Text:
1. A semiconductor device comprising: a semiconductor chip including a schottky barrier diode and a plurality of power MOSFETs which are formed on a semiconductor substrate, wherein the semiconductor substrate includes 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, wherein the schottky barrier diode is formed in a first region of the semiconductor substrate and includes an anode electrode and a cathode electrode, wherein the plurality of power MOSFETs are formed in a plurality of second regions of the semiconductor substrate and respectively include a gate electrode, a source region and a drain region, wherein a first metal layer is formed over the semiconductor substrate, is electrically connected to the gate electrodes and surrounds the first region and the second regions in a planar view, wherein a plurality of gate fingers are unified with the first metal layer, are extending to a direction along the first short side and are arranged between each of the second regions, wherein a second metal layer is formed over the first region and the second regions and is electrically connected to the source regions and the anode electrode, and wherein a length along the first long side of the first region is larger than a length along the first short side of the first region.
