Abstract
A method of manufacturing an optoelectronic semiconductor chip includes a) providing a semiconductor layer sequence having an active region that generates or receives radiation on a substrate; b) forming at least one recess extending through the active region; c) forming a metallic reinforcement layer on the semiconductor layer sequence by galvanic deposition, the metallic reinforcement layer completely covering the semiconductor layer sequence and at least partially filling the recess; and d) removing the substrate, wherein the metallic reinforcement layer is leveled on a side facing away from the semiconductor layer sequence.
