Title (EN) LOW WETTING HYSTERESIS HYDROPHOBIC SURFACE COATING, METHOD FOR DEPOSITING SAME, MICROCOMPONENT AND USE
(FR) REVETEMENT DE SURFACE HYDROPHOBE ET A FAIBLE HYSTERESIS DE MOUILLAGE, PROCEDE DE DEPOT D'UN TEL REVETEMENT, MICRO-COMPOSANT ET UTILISATION
Abstract:
(EN) The invention concerns a surface coating, preferably obtained by chemical vapour deposition, comprising at least one upper thin coat (6) consisting of a compound selected among SiCXOY:H: with x ranging between 1.4 and 2 and y ranging between 0.8 and 1.4 and SiCX'NY': H: with x' ranging between 1.2 and 4 and y ranging between 0.6 and 0.8, so as to obtain a free surface with low wetting hysteresis. Such a hydrophobic surface coating (6) can be arranged on the free surface of a microcomponent comprising at least one substrate (1) provided with an array of electrodes (4) and particularly adapted for moving liquid drops by electrowetting on dielectric.
(FR) Un revêtement de surface hydrophobe, de préférence réalisé par dépôt chimique en phase vapeur, comporte au moins une couche mince supérieure (6) constituée par un composé choisi parmi SiCXOY:H avec x compris entre 1, 4 et 2 et y compris entre 0, 8 et 1, 4 et SiCX'NY': H avec x' compris entre 1, 2 et 1, 4 et y' compris entre 0, 6 et 0, 8, de manière à obtenir une surface libre à faible hystérésis de mouillage. Un tel revêtement de surface hydrophobe (6) peut être disposé sur la surface libre d'un micro-composant comportant au moins un substrat (1) muni d'un réseau d'électrodes (4) et particulièrement adapté au déplacement de goutte de liquide par électromouillage sur diélectrique.
