Title (EN) METHODS FOR PREPARING ELECTRICALLY CONDUCTIVE PATTERNS AND ARTICLES CONTAINING ELECTRICALLY CONDUCTIVE PATTERNS
(FR) PROCÉDÉS DE PRÉPARATION DE MOTIFS ÉLECTRIQUEMENT CONDUCTEURS ET ARTICLES CONTENANT DES MOTIFS ÉLECTRIQUEMENT CONDUCTEURS
Abstract:
(EN) Conductive articles include an electrically insulating substrate with conductive regions on the substrate, the conductive regions are conductive patterns of a transparent conductor and a resist matrix. The substrate also has non-conductive regions, and exposed conductive contacts, where the conductive contacts are in electrical contact with the conductive regions. The non-conductive regions are formed by selective chemical etching of the transparent conductor coating, where the selective etching does not remove the conductive patterns or conductive contact.
(FR) La présente invention concerne des articles conducteurs qui comprennent un substrat électriquement isolant, des régions conductrices se trouvant sur le substrat, les régions conductrices étant des motifs conducteurs d'un conducteur transparent et d'une matrice de réserve. Le substrat comporte également des régions non conductrices, et des contacts conducteurs exposés, les contacts conducteurs étant en contact électrique avec les régions conductrices. Les régions non conductrices sont formées par gravure chimique sélective du revêtement conducteur transparent, la gravure sélective ne retirant pas les motifs conducteurs ou le contact conducteur.
