Abstract

Procédé pour déposer une couche pyroélectrique (200), en polyfluorure de vinylidène ou en un de ses copolymères, sur un substrat (104) en verre ou en polymère, recouvert localement par un motif (108), en oxyde métallique et/ou en métal, le procédé comprenant les étapes successives suivantes :a) fourniture d’un substrat (104), en verre ou en polymère, recouvert localement par un motif (108) en oxyde métallique et/ou en métal,b) dépôt sur le motif (108), de molécules ayant au moins un groupement thiol, de manière à former une couche de molécules (400) sur le motif (108),c) gravure du substrat avec un plasma comprenant au moins 50% volumique de SF6,d) dépôt d’une couche pyroélectrique (200) en polyfluorure de vinylidène ou en de ses copolymères sur le substrat (104) gravé. Figure pour l’abrégé : figure 3d.
