As a result, the surface area of the adhesive surface of the deformable adhesive stamp is adjusted and thus the removal of the semiconductor chips from the chip-receiving surface of the volume area is made possible.
- the idea is to achieve good adhesion between the adhesive stamp and the semiconductor chip when it is removed from the source carrier and when the semiconductor chips are placed on the target carrier, the adhesion between the adhesive surface of the adhesive stamp and the semiconductor chip must be low. It is advantageously possible to dispense with shear movements when the semiconductor chips are deposited and the material for the surface of the target carrier can thus be chosen more freely.

This means that the method does not have to transmit all of the semiconductor chips provided on the source carrier. Instead, the method enables only a selected part of the semiconductor chips arranged on the source carrier to be transmitted. This makes possible,
- Selected parts of the semiconductor chips for example as functional semiconductor chips, can then be transferred simultaneously from the source carrier to the target carrier.
