Title (EN) PLASMA ETCHING METHOD USING IMPRINTED MICROPATTERN
(FR) PROCÉDÉ DE GRAVURE AU PLASMA UTILISANT UN MICROMOTIF IMPRIMÉ
(KO) 임프린트된 미세 패턴을 이용한 플라즈마 에칭 방법
Abstract:
(EN) The present invention provides a plasma etching method using an imprinted micropattern, the method comprising the steps of: applying an ultraviolet resin to the upper surface of a metal layer formed on a glass substrate, forming a micropattern on the ultraviolet resin through an imprinting process of pressing a micropattern master, and then irradiating the micropattern with ultraviolet light to cure the micropattern; performing a slope deposition process on one side surface and the upper surface of the cured micropattern to form a micropattern reinforcing part thereon; performing a first plasma etching process to remove the ultraviolet resin in an area where the micropattern reinforcing part is not formed to expose the micropattern in the vertical direction; performing a second plasma etching process to remove a metal layer in an area where the metal layer is exposed in the vertical direction; and removing the micropattern and the micropattern reinforcing part remaining on the metal layer from which the vertically exposed area has been removed.
(FR) La présente invention concerne un procédé de gravure au plasma utilisant un micromotif imprimé, le procédé comprenant les étapes consistant à: appliquer une résine ultraviolette sur la surface supérieure d'une couche métallique formée sur un substrat de verre, former un micromotif sur la résine ultraviolette par l'intermédiaire d'un processus d'impression consistant à presser un modèle de micromotif, puis irradier le micromotif avec une lumière ultraviolette pour durcir le micromotif; réaliser un processus de dépôt en pente sur une surface latérale et la surface supérieure du micromotif durci pour former une partie de renforcement de micromotif sur celle-ci; réaliser un premier processus de gravure au plasma pour retirer la résine ultraviolette dans une zone où la partie de renforcement de micromotif n'est pas formée pour exposer le micromotif dans la direction verticale; réaliser un second processus de gravure au plasma pour retirer une couche métallique dans une zone où la couche métallique est exposée dans la direction verticale; et retirer le micromotif et la partie de renforcement de micromotif restant sur la couche métallique à partir de laquelle la zone exposée verticalement a été retirée.
(KO) 본 발명은 유리 기판 상에 형성된 금속층의 상면에 자외선 레진을 도포하고 미세 패턴 마스터를 가압하는 임프린팅 공정을 수행하여 상기 자외선 레진에 미세 패턴을 형성한 후에 자외선을 조사하여 상기 미세 패턴을 경화시키는 단계, 상기 경화된 미세 패턴의 일 측면과 상면에 경사 증착 공정을 수행하여 미세 패턴 강화부를 형성하는 단계, 제 1 플라즈마 에칭 공정을 수행하여 상기 미세 패턴 중에서 상기 미세 패턴 강화부가 형성되지 않아 수직 방향으로 노출되어 있는 영역의 자외선 레진을 제거하는 단계, 제 2 플라즈마 에칭 공정을 수행하여 상기 금속층 중에서 수직 방향으로 노출되어 있는 영역의 금속층을 제거하는 단계 및 상기 수직방향으로 노출된 영역이 제거된 금속층의 상부에 잔존하는 미세 패턴 및 미세 패턴 강화부를 제거하는 단계를 포함하는 임프린트된 미세 패턴을 이용한 플라즈마 에칭 방법을 제공한다.
