  • Patent number: 9680049
    Abstract: In at least one embodiment, a method is designed to produce optoelectronic semiconductor chips. A carrier assembly, which is a sapphire wafer, is produced. A semiconductor layer sequence is applied to the carrier assembly. The carrier assembly and the semiconductor layer sequence are divided into the individual semiconductor chips. The dividing is implemented by producing a multiplicity of selectively etchable material modifications in the carrier assembly in separation region(s) by focused, pulsed laser radiation. The laser radiation has a wavelength at which the carrier assembly is transparent. The dividing includes wet chemically etching the material modifications, such that the carrier assembly is singulated into individual carriers for the semiconductor chips solely by the wet chemical etching or in combination with a further material removal method.
