Abstract:
1. A method for the production of a plurality of optoelectronic semiconductor chips each having a plurality of structural elements with respectively at least one semiconductor layer, the method comprising the steps of: providing a chip composite base having a substrate and a growth surface; growing a non-closed mask material layer onto the growth surface in such a way that the mask material layer has a plurality of statistically distributed windows having varying forms and/or opening areas, a mask material being chosen in such a way that a semiconductor material of the semiconductor layer that is to be grown in a later method step essentially cannot grow on said mask material or can grow in a substantially worse manner in comparison with the growth surface; essentially simultaneously growing semiconductor layers on regions of the growth surface that lie within the windows; and singulating the chip composite base with applied material to form semiconductor chips each having the plural structural elements arranged alongside one another, the structural elements comprising a semiconductor layer sequence.
