Claim:
1. A method for singulating an assemblage into a plurality of semiconductor chips comprising the following steps: a) providing an assemblage comprising a carrier, a semiconductor layer sequence and a metallic layer; b) forming separating trenches in the carrier; and c) subjecting the assemblage to mechanical loading, with the result that the metallic layer breaks along the separating trenches and the assemblage is singulated into semiconductor chips, wherein the singulated semiconductor chips each have part of the semiconductor layer sequence, of the carrier and of the metallic layer, wherein the metallic layer is arranged between the semiconductor layer sequence and the carrier, wherein after step b) the metallic layer is the only layer of the assemblage via which carrier bodies of the carrier are still mechanically stably connected to one another and wherein the metallic layer remains in the singulated and completed semiconductor chips.
