Patent ID: 8003996

Claim:
A method for manufacturing a semiconductor component emitting two different wavelengths (λ 1 , λ 2 ), having a defined intensity ratio (I 2 /I 1 ), comprising: providing a substrate ( 8 ), applying a first charge carrier barrier layer ( 7 ) to the top side of the substrate ( 8 ), applying a photoluminescent layer ( 6 ) to the first charge carrier barrier layer ( 7 ), applying a reflective layer ( 5 ) to the photoluminescent layer ( 6 ), such that the reflective layer ( 5 ) is also designed as a second charge carrier barrier layer ( 5 ), applying an active electroluminescent layer ( 4 ) of at least one inorganic semiconductor to the reflective layer ( 5 ), such that the photoluminescent layer ( 6 ) absorbs at least a portion of the light emitted by the active electroluminescent layer ( 4 ), and applying an at least partially transparent contact layer ( 1 ) to the active electroluminescent layer ( 4 ), such that the substrate ( 8 ), the first charge carrier barrier layer ( 7 ), the photoluminescent layer ( 6 ), the reflective layer ( 5 ), the active electroluminescent layer ( 4 ) and the at least partially transparent contact layer ( 1 ) are each formed by a semiconducting material, wherein the reflective layer ( 5 ) is designed with a reflectivity of more than 80% for the wavelength (λ 1 ) of the electroluminescent light emitted by the active electroluminescent layer ( 4 ).
