Abstract:
1. A semiconductor chip comprising: a semiconductor body comprising a semiconductor layer sequence with an active region provided for generating radiation; a mirror structure arranged on the semiconductor body, the mirror structure comprising a mirror layer and a dielectric layer structure arranged at least in regions between the mirror layer and the semiconductor body, wherein the dielectric layer structure has at least one cutout; and a contact structure arranged in the at least one cutout of the dielectric layer structure, wherein the contact structure comprises a reflector layer that contains a metal or a metallic alloy and is arranged closer to the semiconductor body than the mirror layer, and wherein the contact structure comprises a layer containing a transparent conductive oxide material, said layer containing transparent conductive oxide material being arranged in the at least one cutout between the semiconductor body and the reflector layer, wherein the transparent oxide material and the reflector layer are arranged only in the at least one cutout.
