Abstract: An electromagnetic radiation emitting device and a method for applying a converter layer to an electromagnetic radiation emitting device are disclosed. In an embodiment, a method includes applying converter elements to a surface of a carrier, applying the converter elements to an electromagnetic radiation emitting device by applying the carrier to the electromagnetic radiation emitting device such that the surface of the carrier with the applied converter elements faces the electromagnetic radiation emitting device and forming a converter layer on the electromagnetic radiation emitting device by depositing a plurality of thin layers on the converter elements using an atomic layer deposition process.

Abstract: A light-emitting semiconductor component may include a semiconductor body having an active region configured to emit a primary radiation, a first conversion element to convert the primary radiation to a first secondary radiation, a second conversion element to convert the primary radiation to a second secondary radiation, and a mask. The first conversion element and the second conversion element may be arranged at a top side of the semiconductor body, may be configured as bodies that partly cover the semiconductor body, and may be connected to the semiconductor body. The mask may be arranged between the first conversion element, the second conversion element, and the semiconductor body. The mask may have an opening in the region of each conversion element.
