Patent ID: 8110886

Claim:
A monolithic electric component, comprising: a crystalline semiconductor body; a laminar structure comprising an n-doped layer and a p-doped layer forming a semiconductor junction of a diode; a dielectric separation layer disposed between the crystalline semiconductor body and the laminar structure; an integrated circuit having at least two terminals disposed on an upper side of the crystalline semiconductor body opposite to the dielectric separation layer; a feedthrough comprising a metallization connecting one of the at least two terminals of the integrated circuit to the laminar structure; a rear-side contact region disposed in the laminar structure adjacent to the semiconductor junction, wherein the rear-side contact region is configured as a closed annular trench enclosing a surface of the diode; a trench insulation surrounding the rear-side contact region on both sides to insulate the rear-side contact from the remaining laminar structure; and a further feedthrough comprising a further metallization connecting another of the at least two terminals of the integrated circuit to the rear-side contact region, wherein a rear side of the laminar structure opposite to the dielectric separation layer is available for incident light.
