Title
(EN) SOLID ELECTROLYTIC CAPACITOR AND METHOD OF MANUFACTURING A SOLID ELECTROLYTIC CAPACITOR
(FR) CONDENSATEUR À ÉLECTROLYTE SOLIDE ET PROCÉDÉ DE FABRICATION D'UN CONDENSATEUR À ÉLECTROLYTE SOLIDE
Abstract
(EN)
Provided is a method for forming a capacitor. The method includes: providing an anode with a dielectric thereon and a conductive node in electrical contact with the anode; applying a conductive seed layer on the dielectric; forming a conductive bridge between the conductive seed layer and the conductive node; applying voltage to the anode; electrochemically polymerizing a monomer thereby forming an electrically conducting polymer of monomer on the conductive seed layer; plating a metal layer on said conductive polymer; and disrupting the conductive bridge between the conductive seed layer and the conductive node.
(FR)
La présente invention concerne un procédé de formation d'un condensateur. Le procédé fait appel : à l'utilisation d'une anode portant un diélectrique et d'un nœud conducteur en contact électrique avec l'anode ; à l'application d'une couche de germe conductrice sur le diélectrique ; à la formation d'un pont conducteur entre la couche de germe conductrice et le nœud conducteur ; à l'application d'une tension à l'anode ; à la polymérisation électrochimique d'un monomère, formant ainsi un polymère électriquement conducteur de monomère sur la couche de germe conductrice ; au placage d'une couche métallique sur ledit polymère conducteur ; et à la rupture du pont conducteur entre la couche de germe conductrice et le nœud conducteur.
