Abstract
A method of manufacturing an optoelectronic component includes providing a carrier with an upper side; arranging an optoelectronic semiconductor chip above the upper side of the carrier; arranging a casting material above the upper side of the carrier, wherein the optoelectronic semiconductor chip is embedded in the casting material, and the casting material forms a cast surface; simultaneously spraying particles and a further material onto the cast surface, wherein a mixture of the further material and the particles includes a proportion of the particles of 20 percent by weight to 60 percent by weight, a portion of the particles remains at the cast surface, and a topography is created at the cast surface.
