Abstract
In an embodiment an electronic semiconductor chip includes a growth substrate with a growth surface including a flat region having a plurality of three-dimensionally designed surface structures on the flat region, a nucleation layer composed of oxygen-containing AlN in direct contact with the growth surface at the flat region and the three-dimensionally designed surface structures and a nitride-based semiconductor layer sequence on the nucleation layer, wherein the semiconductor layer sequence overlays the three-dimensionally designed surface structures, and wherein the oxygen content in the nucleation layer is greater than 10cm.
