Zusammenfassung:A method of selecting semiconductor chips includes: A) providing the semiconductor chips in a composite, B) producing a cohesive, mechanical first connection between the semiconductor chips and a carrier film, C) singulating the semiconductor chips, wherein the carrier film mechanically connects the semiconductor chips to one another after singulation, D) selectively weakening the first connection between some singulated semiconductor chips and the carrier film, depending on electro-optical and or electrical properties of the semiconductor chips, and E) removing the semiconductor chips whose first connection is selectively weakened from the carrier film.
