Abstract
A semiconductor device of embodiments includes: an element region including a transistor, a first diode, and a first contact portion; a termination region surrounding the element region and including a second contact portion; and an intermediate region provided between the element region and the termination region and not including the transistor, the first diode, the first contact portion, and the second contact portion. The element region includes a first electrode, a second electrode, a gate electrode, a silicon carbide layer, and a gate insulating layer. The termination region includes a first wiring layer electrically connected to the first electrode, the second electrode, and the silicon carbide layer. The intermediate region includes the silicon carbide layer. The width of the intermediate region in a direction from the element region to the termination region is equal to or more than twice the thickness of the silicon carbide layer.
