Claim 6:
7. A process for the production of a capacitor, comprising the process steps:
I) providing an electrode body comprising an electrode material, wherein a dielectric comprising a dielectric material covers a surface of this electrode material at least partially;
II) depositing a solid electrolyte layer comprising a solid electrolyte material onto at least a part of a surface of the dielectric layer, wherein the solid electrolyte material comprises a conductive polymer;
III) bringing the electrode body in contact with an anode contact that comprises copper, metal-plated copper or a copper-containing alloy; and
IV) bringing the solid electrolyte layer in contact with a cathode contact;, wherein at least one metal ion migration inhibitor being able to form a chelate-complex with copper ions is introduced into the solid electrolyte layer or is applied onto the surface of the solid electrolyte layer.
