Abstract
A method for producing an electronic semiconductor chip and a semiconductor chip are disclosed. In embodiments, the method includes providing a growth substrate having a growth surface formed by a flat region having a plurality of three-dimensional surface structures on the flat region, directly applying a nucleation layer of oxygen-containing AlN over a large area to the growth surface and growing a nitride-based semiconductor layer sequence on the nucleation layer, wherein growing the semiconductor layer sequence includes selectively growing the semiconductor layer sequence upwards from the flat region.
