A method for producing an output coupling element and an optoelectronic component are disclosed. In an embodiment, a method includes providing an inorganic dielectric element with a surface in a chamber, wherein the inorganic dielectric element rotates in the chamber during operation and providing a structuring agent comprising water and ozone and introducing the structuring agent into the chamber so that the structuring agent contacts the surface of the inorganic dielectric element and a roughening is produced in the surface, wherein the inorganic dielectric element comprises aluminum oxide.

Method for producing an output coupling element for an optoelectronic component and optoelectronic component

A process for structuring at least one layer as well as an electrical component with structures from the layer are described. The invention states a process to generate at least one structured layer (A), wherein a mask structure () with a first (A) and second structure (B) is generated on a layer () which is present on a substrate (). Through this mask structure (), the first layer (A) is transferred onto the layer () using isotropic structuring processes, and the second structure (B) is transferred onto the layer () using anisotropic structuring processes. The process as per the invention permits the generation of two structures (A,B) in at least a single layer while using a single mask structure.
