Abstract
A semiconductor chip is disclosed. In an embodiment a semiconductor chip includes a multiply-connected mask layer comprising openings, the openings completely penetrate the mask layer and a semiconductor layer sequence, which, at least in places, is in direct contact with the mask layer, wherein the semiconductor layer sequence is disposed on the mask layer, wherein the mask layer comprises a light-transmissive material, and wherein the light-transmissive material comprises an optical refractive index for light which is smaller than a refractive index of the semiconductor layer sequence.
