Measuring device and method for determining the course of a bonding wave

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 the exposure of image points of a photosensitive layer comprising a photosensitive material on a substrate by means of an optical system. The method including continuously moving the image points with respect to the optical system; and controlling a plurality of secondary beams by means of the optical system individually for individual exposures of each image point, whereby the secondary beams are put either into an ON state or into an OFF state, wherein a) secondary beams in the ON state produce an individual exposure of the image point assigned to the respective secondary beam and b) secondary beams in the OFF state do not produce any individual exposure of the image point assigned to the respective secondary beam; wherein, for the generation of image points with grey tones n&#x3e;1, individual exposures are carried out by different secondary beams with individual doses D.

Method and apparatus for illuminating image points

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.
