Title (EN) METHOD OF ETCHING
(FR) PROCÉDÉ DE GRAVURE
Abstract: front page image
(EN)A method of selectively removing material from a surface, the method comprising the steps of: providing the surface with at least one open channel, the channel defining the region where material is to be removed; and depositing a flowable etchant adjacent to the said at least one open channel, such that the etchant is drawn into the channel by capillary forces, material being transferred from the surface into the etchant.
(FR)La présente invention concerne un procédé pour éliminer sélectivement un matériau d’une surface, le procédé comprenant les étapes qui consistent : à ménager sur la surface au moins un canal ouvert définissant la région où du matériau doit être éliminé; et à déposer un agent de gravure liquide de façon adjacente audit ou auxdits canaux ouverts, de sorte que l’agent de gravure soit aspiré dans le canal par des forces capillaires, le matériau étant transféré de la surface à l’agent de gravure.
