摘要： An optoelectronic semiconductor chip includes a semiconductor layer sequence having an active layer and a light-outcoupling layer applied at least indirectly on a radiation permeable surface of the semiconductor layer sequence. A material of the light-outcoupling layer is different from a material of the semiconductor layer sequence and refractive indices of the materials of the light-outcoupling layer and of the semiconductor layer sequence differ from each other by 20% at most. Recesses in the light-outcoupling layer form facets, wherein the recesses do not penetrate the light-outcoupling layer completely. The facets have a total area of at least 25% of an area of the radiation permeable surface.
