Abstract:
1. 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 including an anode electrode and a cathode electrode; and the plurality of power MOSFETs formed in a plurality of second regions of the semiconductor substrate and respectively including 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 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.
