The invention relates to a device for the transfer of a transfer layer from a substrate, in particular from a growth substrate, to a carrier substrate.

Method and device for transferring a transfer layer

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.

Device and method for separating a temporarily bonded substrate stack

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.
