Abstract
A semiconductor device includes a semiconductor substrate having an active region in which a main switching element structure is formed, a current sense region in which a sense switching element structure is formed, and a peripheral region located around the active region and the current sense region. The semiconductor substrate is a 4H-SiC substrate having an off angle in a <11-20> direction. The current sense region is disposed in a range where the active region is not present when viewed along the <1-100> direction.
