Abstract
A semiconductor device and a method for manufacturing the semiconductor device. The semiconductor device includes a silicon carbide substrate and a protective film covering at least partly a main surface of the silicon carbide substrate and one or more side surfaces of the silicon carbide substrate. Therefore, contact of the side surface of the silicon carbide substrate with the moisture gathering material may be avoided, and the breakdown behavior and the long-term reliability of the semiconductor device may be further improved.
