Title
(EN) NON-CONTACT TRANSFER PRINTING
(FR) IMPRESSION PAR TRANSFERT SANS CONTACT
Abstract
(EN)
A transfer printing process that exploits the mismatch in mechanical or thermo-mechanical response at the interface of a printable micro- or nano-device and a transfer stamp to drive the release of the device from the stamp and its non-contact transfer to a receiving substrate are provided. The resulting facile, pick-and-place process is demonstrated with the assembling of 3-D microdevices and the printing of GAN light-emitting diodes onto silicon and glass substrates. High speed photography is used to provide experimental evidence of thermo-mechanically driven release.
(FR)
L'invention porte sur un procédé d'impression par transfert qui exploite le décalage dans la réponse mécanique ou thermomécanique à l'interface d'un microdispositif ou nanodispositif imprimable et d'un tampon transfert pour entraîner la libération du dispositif du tampon et son transfert sans contact sur un substrat de réception. Le procédé facile de transfert par preneur-placeur résultant est démontré par l'assemblage de microdispositifs en 3 dimensions et l'impression de diodes électroluminescentes de réseau global (GAN) sur des substrats de silicium et de verre. Une photographie ultra rapide est utilisée pour fournir une preuve expérimentale de la libération entraînée de façon thermomécanique.
