Abstract:
A radiation-emitting semiconductor body with a carrier substrate and a method for producing the same. In the method, a structured connection is produced between a semiconductor layer sequence (2) and a carrier substrate wafer (1). The semiconductor layer sequence is subdivided into a plurality of semiconductor layer stacks (200) by means of cuts (6) through the semiconductor layer sequence, and the carrier substrate wafer (1) is subdivided into a plurality of carrier substrates (100) by means of cuts (7) through the carrier substrate wafer (1). In the method, the structured connection is formed in such a way that at least one semiconductor layer stack (200) is connected to one and only one associated carrier substrate (100). In addition, at least one cut (7) through the carrier substrate wafer is not extended by any of the cuts (6) through the semiconductor layer sequence such that a straight cut results through the carrier substrate wafer and the semiconductor layer sequence.
