摘要:
A light-emitting diode chip having a semiconductor layer sequence having an active layer that generates electromagnetic radiation, wherein the light-emitting diode chip has, on a front side, a radiation exit surface, at least regions of the light-emitting diode chip have, on a rear side opposite the radiation exit surface, a mirror layer containing silver, a protective layer containing Pt is disposed on the mirror layer, and the protective layer has a structure that covers the mirror layer only in sub-regions.
