Abstract:
1. An optoelectronic semiconductor chip comprising: a semiconductor layer stack having an active layer that generates radiation, and a radiation emission side, and a conversion layer disposed on the radiation emission side the semiconductor layer stack, wherein the conversion layer converts at least a portion of the radiation, which is emitted by the active layer, into radiation of a different wavelength, the radiation emission side of the semiconductor layer stack has a first nanostructuring, the conversion layer is only disposed in the first nanostructuring so that a top side of the nanostructuring is free of the conversion layer and so that the nanostructuring is completely filled with the conversion layer, wherein the first nanostructuring is composed of a plurality of nanorods and recesses and the top side is a side remote from a continuous layer of the semiconductor layer stack, and the active layer only covers all lateral surfaces and base surfaces of the recesses so that the top side of the nanostructuring is free of the active layer.
