Title:
CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2001/091145
Kind Code:
A1
Abstract:
A capacitor comprises a porous metal sheet, part of which forms an electrode; an organic dielectric material formed on the metal surface; a solid electrolyte layer formed on the organic dielectric material; an electrode layer formed on the solid electrolyte layer; and a protective insulating layer for protecting the electrode, the dielectric material, the solid electrolyte layer and the electrode layer. Bumps are formed on the protective insulating layer and connected to the electrode and/or the electrode layer. A semiconductor device or a circuit with improved high-frequency response can be manufactured using such a capacitor.
