Title
(EN) A METHOD OF LAYER DEPOSITION
(FR) PROCÉDÉ DE DÉPÔT DE COUCHE
Abstract
(EN)
A method for forming an electronic device by depositing a patterned surface coating of a coating material on a target substrate, the method employing a transfer tool having a patterned relief that defines a patterned transfer surface of the transfer tool, the method comprising: forming a layer of the coating material on a donor substrate; in a collecting step, offering the transfer surface to the donor substrate so as to cause coating material on the donor substrate to adhere to the transfer surface; in a separating step, moving the transfer surface and the donor substrate away from each other with coating material adhering to the transfer surface; in a depositing step, offering the transfer surface to the target substrate so as to cause coating material on the transfer surface to adhere to the target substrate; and in a return step, moving the transfer surface and the target substrate away from each other with coating material adhering to the target substrate; wherein the material of the transfer tool that defines the transfer surface is harder than the donor substrate.

L'invention concerne un procédé de formation d'un dispositif électronique par dépôt d'un revêtement de surface à motifs d'un matériau de revêtement sur un substrat cible, le procédé utilisant un outil de transfert ayant un relief à motifs qui définit une surface de transfert à motifs de l'outil de transfert, le procédé comprenant : la formation d'une couche du matériau de revêtement sur un substrat donneur ; dans une étape de collecte, la fourniture de la surface de transfert au substrat donneur de façon à amener le matériau de revêtement sur le substrat donneur à adhérer à la surface de transfert ; dans une étape de séparation, la séparation de la surface de transfert et du substrat donneur l'une de l'autre avec un matériau de revêtement adhérant à la surface de transfert ; dans une étape de dépôt, la fourniture de la surface de transfert au substrat cible de façon à amener le matériau de revêtement sur la surface de transfert à adhérer au substrat cible ; et dans une étape de retour, la séparation de la surface de transfert et du substrat cible l'une de l'autre avec un matériau de revêtement adhérant au substrat cible ; le matériau de l'outil de transfert qui définit la surface de transfert étant plus dur que le substrat donneur.
