Abstract
A semiconductor device according to an embodiment includes a semiconductor chip having a transistor region and a diode region, and a conductor. The semiconductor chip includes a first electrode, a second electrode, a silicon carbide layer between the first electrode and the second electrode, and a gate electrode. The first electrode includes a first region in the transistor region and a second region in the diode region. A first contact area between the conductor and the first region is larger than a second contact area between the conductor and the second region.
