Abstract:
A method of producing a conversion element includes providing a substrate having a surface; forming a first mask structure above the surface, wherein the first mask structure has first webs and first openings arranged between the first webs and the first openings form cavities in which the surface of the substrate is accessible; arranging a second mask structure above the first mask structure, wherein the second mask structure has second webs and second openings arranged between the second webs, the first webs are at least partly covered by the second webs, and the cavities remain at least partly accessible through the second openings; spraying a material into the cavities through the second openings; removing the second mask structure; and removing the first mask structure.
