Method for producing an optoelectronic component, optoelectronic component, and component arrangement having a plurality of optoelectronic components

摘要

A method for producing optoelectronic components including A) providing a growth substrate with a semiconductor layer arranged thereon that produces a zone which is active during operation, B) applying separating structures on the semiconductor layer, C) applying a multiplicity of copper layers on the semiconductor layer in regions delimited by the separating structures, D) removing the separating structures, E) applying, a protective layer at least on lateral areas of copper layers, F) applying an auxiliary substrate on the copper layers, G) removing the growth substrate, H) singulating a composite assembly comprising the semiconductor layer, the copper layers and the auxiliary substrate to form components which are separated from one another.

1. An optoelectronic component comprising a semiconductor layer arranged on a copper layer, wherein
the copper layer is formed as a carrier substrate for the semiconductor layer, an entire exposed surface of the copper layer having horizontal and lateral surfaces is coated with a metal layer, wherein the lateral areas of the copper layer are covered completely with the metal layer, and only lateral portions of the metal layer covering the lateral areas of the copper layer are oxidized so that a protective layer is formed on the lateral areas of the copper layer, wherein the protective layer is a metal oxide layer which prevents copper migration into the semiconductor layer.
