Abstract:
1. A method for the production of a conversion die, which is configured to convert electromagnetic radiation of a first wavelength range into electromagnetic radiation of a second wavelength, said method comprising the steps of: providing a substrate; applying a structured photoresist layer on the substrate; depositing a conversion layer of a conversion material over the photoresist layer by one of the following methods: Pulsed-Laser-Deposition, sputtering, e-beam deposition, ion beam assisted pulsed laser deposition, aerosol deposition; and removing the photoresist layer, such that discrete conversion dies are formed on the substrate; wherein the substrate comprises a sacrificial layer comprising one of a nitride based material and an oxide based material, the substrate and the conversion dies being separated from each other by removing the sacrificial layer.
