  • Device and method for separating a temporarily bonded substrate stack
    Patent number: 11534868
    Abstract: A method for separating a temporarily bonded substrate stack by bombardment of a joining layer of the substrate stack by means of laser beams emitted by a laser, characterised in that laser beams of the laser reflected and/or transmitted at the temporarily bonded substrate stack are detected during the bombardment of the joining layer with the laser beams. The invention also relates to a corresponding device.

  • Method for producing a polychromatizing layer and substrate and also light-emitting diode having a polychromatizing layer
    Patent number: 9202993
    Abstract: The invention relates to a method for applying a polychromatizing layer which contains at least one luminescent means on a semiconductor substrate, which layer is suitable for producing a monochromatic light. The polychromatizing layer is applied with a printing process, especially with a micro-contact printing process. Preferably the polychromatizing layer is applied structured.
