Abstract: The photodetector is formed in a silicon carbide body formed by a first epitaxial layer of an N type and a second epitaxial layer of a P type. The first and second epitaxial layers are arranged on each other and form a body surface including a projecting portion, a sloped lateral portion, and an edge portion. An insulating edge region extends over the sloped lateral portion and the edge portion. An anode region is formed by the second epitaxial layer and is delimited by the projecting portion and by the sloped lateral portion.

A buried region of an N type, with a higher doping level than the first epitaxial layer, extends between the anode and cathode regions, underneath the projecting portion, at a distance from the sloped lateral portion as well as from the edge region.
