Abstract
A method is provided for producing a radiation-emitting semiconductor chip, in which a first wavelength-converting layer is applied over the radiation exit face of a semiconductor body. The application method is selected from the following group: sedimentation, electrophoresis. In addition, a second wavelength-converting layer is applied over the radiation exit face of the semiconductor body. The second wavelength-converting layer is either produced in a separate method step and then applied or the application method is sedimentation, electrophoresis or printing. Furthermore, a radiation-emitting semiconductor chip and a radiation-emitting component are provided.
