Title (EN) METHOD FOR FORMING A MICRO-PATTERN ON A SUBSTRATE BY USING CAPILLARY FORCE
(FR) PROCEDE DE FORMATION D'UN MICROMOTIF SUR UN SUBSTRAT, PAR FORCE CAPILLAIRE
Abstract:
(EN) In a method for forming a micro-pattern on a substrate by employing a mold having a predetermined pattern structure, a mold having a predetermined pattern structure containing a recessed portion and a protruded portion is prepared. A polymer material is deposited on the substrate. Then the protruded portion of the mold is controlled to be in contact with the polymer material and the polymer material in contact with the protruded portion of the mold is incorporated into an empty space of the recessed portion thereof by using capillary force thereof, thereby removing the polymer material in contact with the protruded portion of the mold. Thereafter, a portion of the top surface of the substrate is exposed by detaching the mold to thereby form a polymer micro-pattern on the substrate.
(FR) L'invention concerne un procédé destiné à la formation d'un micromotif sur un substrat à l'aide d'un moule possédant une structure de motif prédéterminée, consistant à préparer un moule possédant une structure de motif prédéterminée comportant une partie en retrait et une partie en relief. Ce procédé consiste à déposer un polymère sur le substrat, à vérifier que la partie en relief du moule est en contact avec le polymère, puis à introduire, par force capillaire, le polymère en contact avec la partie en relief du moule dans un espace vide de la partie en retrait du moule, afin que le polymère ne soit plus en contact avec la partie en relief du moule. Ce procédé consiste ensuite à retirer le moule afin d'exposer une partie de la surface supérieure du substrat et à former un micromotif polymère sur le substrat.
