Abstract
According to the present disclosure, optoelectronic semiconductor chip includes at least one n-doped semiconductor layer, at least one p-doped semiconductor layer and one active layer arranged between the at least one n-doped semiconductor layer and the at least one p-doped semiconductor layer. The p-doped semiconductor layer is electrically contacted by means of a first metallic connection layer, and a reflection-enhancing dielectric layer sequence is arranged between the p-doped semiconductor layer and the first connection layer, which dielectric layer sequence includes a plurality of dielectric layers with different refractive indices.
