An embodiment of a semiconductor device includes a semiconductor body having a first main surface. The semiconductor body includes an active device area and an edge termination area at least partly surrounding the active device area. The semiconductor device further includes a contact electrode on the first main surface and electrically connected to the active device area. The semiconductor device further includes a passivation structure on the edge termination area and laterally extending into the active device area. The semiconductor device further includes an encapsulation structure on the passivation structure and covering a first edge of the passivation structure above the contact electrode.
