Abstract
A method for producing a plurality of semiconductor chips and a semiconductor chip are disclosed. The method includes applying a mask material on a growth surface of a growth substrate, wherein the growth surface includes sapphire, patterning the mask material into a multiply-connected mask layer by introducing openings into the mask material, wherein the growth surface is exposed at the bottom of at least some of the openings, applying a semiconductor layer sequence on the mask layer and on the growth surface and singulating at least the semiconductor layer sequence into the plurality of semiconductor chips, wherein each semiconductor chip includes lateral dimensions and the lateral dimensions are large compared to an average distance of the openings to the nearest opening.
