Patent ID: 8017416

Claim:
A method for the production of a plurality of optoelectronic semiconductor chips each having a plurality of structural elements with each structural element comprising a semiconductor layer sequence, the method comprising the steps of: providing a chip composite base comprising a substrate and a growth surface; forming on the growth surface a mask material layer with a multiplicity of windows, most of which have an average lateral extent of less than or equal to 1 μm, wherein a mask material is chosen so that a semiconductor material of the semiconductor layer sequence 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, and wherein the windows of the mask material layer comprise a plurality of statistically distributed windows having varying forms and opening areas; essentially simultaneously growing semiconductor layers to form the structural elements 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 a plurality of the structural elements; wherein, after the growth of the semiconductor layers, a layer of electrically conductive contact material that is transmissive to an electromagnetic radiation emitted by an active zone is applied to the semiconductor layers, so that the semiconductor layers of a plurality of the structural elements are electrically conductively connected to one another by the contact material.
