Abstract:
A method of severing a semiconductor device composite includes a carrier having a main surface and a semiconductor layer sequence arranged on the main surface including forming a separating trench in the semiconductor device composite by a first laser cut such that the separating trench only partially severs the semiconductor device composite in a vertical direction running perpendicular to the main surface, and severing the semiconductor device composite completely along the separating trench with a severing cut with a laser.
