Method for producing an optoelectronic semiconductor chip and optoelectronic semiconductor chip |
abstract |
A semiconductor chip and a method for producing a semiconductor chip are disclosed. In an embodiment an electronic semiconductor chip includes a growth substrate with a growth surface, which is formed by a planar region having a plurality of three-dimensional surface structures on the planar region, a nucleation layer composed of oxygen-containing AlN directly disposed on the growth surface and a nitride-based semiconductor layer sequence disposed on the nucleation layer, wherein the semiconductor layer sequence is selectively grown from the planar region such that a growth of the semiconductor layer sequence on surfaces of the three-dimensional surface structures is reduced or non-existent compared to a growth on the planar region, and wherein a selectivity of the growth of the semiconductor layer sequence on the planar region is targetedly adjusted by an oxygen content of the nucleation layer. |
