Abstract
In an embodiment a method includes providing a plurality of radiation-emitting semiconductor chips configured to emit primary radiation of a first wavelength range, applying a converter on the plurality of radiation-emitting semiconductor chips, the converter configured to emit secondary radiation of a second wavelength range, applying a mirror layer sequence arranged downstream of the converter, the mirror layer sequence configured to reflect the primary radiation and transmit the secondary radiation and singulating the plurality of radiation-emitting semiconductor chips in order to produce optoelectronic components, wherein the converter is applied on the plurality of radiation-emitting semiconductor chips by spray coating, and wherein the mirror layer sequence is applied on the converter by sputtering, atomic layer deposition and/or plasma-enhanced chemical vapor deposition (PECVD).
