Abstract
Method for producing semiconductor laser elements () comprises A) providing a carrier composite () having a plurality of carriers () for the semiconductor laser elements (), B) providing a laser bar () having a plurality of semiconductor laser diodes () which comprise a common growth substrate () and a semiconductor layer sequence () grown thereon, C) generating predetermined breaking points () on a substrate underside () of the growth substrate (), said substrate underside facing away from the semiconductor layer sequence (), D) attaching the laser bar () to a carrier upper side () of the carrier composite (), wherein the attachment is performed at an elevated temperature and is followed by cooling, and E) singulating into the semiconductor laser elements (), wherein steps B) to E) are performed in the indicated sequence.
