    摘要: A semiconductor device includes: a passivation film; a first semiconductor layer that has a first main component of 4H—SiC of a first conductivity type; and a second semiconductor layer that has a second main component of 4H—SiC of a second conductivity type. The second semiconductor layer has a pn-junction with the first semiconductor layer. The pn-junction has a junction edge. The first and second semiconductor layers further include a local area that includes the junction edge. The local area has a first principal plane that interfaces with the passivation film. A normal to the first principal plane tilts by a first tilt angle in a range of 25 degrees to 45 degrees from a first axis of [0001] or [000-1] toward a second axis of .
