Abstract
A method of manufacturing an optoelectronic semiconductor chip includes providing a growth substrate, growing a semiconductor layer sequence on the growth substrate, depositing a metallization on a side of the semiconductor layer sequence remote from the growth substrate, depositing a layer on the metallization, coupling a carrier to the layer on a side of the layer remote from the semiconductor layer sequence, separating the growth substrate from the semiconductor layer sequence, depositing an electrically conductive layer on a side of the semiconductor layer sequence facing away from the carrier, separating the carrier from the layer, thereby forming a layer stack with the metallization, the semiconductor layer sequence, the electrically conductive layer and a coupling layer including at least a part of a further material of the layer remaining on a side of the metallization remote from the semiconductor layer sequence, and coupling the layer stack to a chip carrier.
