Claim Text:
1. A silicon carbide device comprising: a silicon carbide substrate; an inorganic passivation layer structure laterally covering at least partly a main surface of the silicon carbide substrate; and a molding material layer adjacent to the inorganic passivation layer structure, wherein the silicon carbide substrate comprises an edge region surrounding an active area of the silicon carbide substrate, wherein the silicon carbide substrate comprises a first conductivity type and at least one edge termination region located within the edge region surrounding the active area of the silicon carbide substrate, wherein the edge termination region has a second conductivity type, wherein the silicon carbide substrate and the inorganic passivation layer structure are configured so that an electric field at a surface of the inorganic passivation layer structure in contact with the molding material layer is lower than 500 kV/cm in an active-state of the silicon carbide device.
