Abstract:
An optoelectronic component, includes a carrier, a metallic mirror layer arranged on the carrier, a first passivation layer arranged on a region of the metallic mirror layer, a semiconductor layer that generates an active region during electrical operation arranged on the first passivation layer, a second passivation layer including two regions, wherein the first region is arranged on a top face of the semiconductor layer, and the second region which is free of the semiconductor layer is arranged on the metallic mirror layer, and wherein the first and second regions are separated from one another by a region which surrounds the first passivation layer and which is free of the second passivation layer.
