Abstract
A capacitor comprising a porous metal sheet, part of which forms an electrode section, an organic dielectrics formed on a metal surface, a solid electrolyte layer formed on the organic dielectrics, an electrode layer formed on the solid electrolyte layer, and an insulating protection layer provided for protecting said electrode section, dielectrics, solid electrolyte layer and electrode layer. The capacitor is provided with bumps, which are formed on the insulating protection layer and connected at least with the electrode section or the electrode layer. The capacitor of the present invention provides a semiconductor device or a circuit superior in the high frequency response.
