Abstract
A multilayer structure in a solid electrolyte capacitor. The multilayer structure extends over a pore and a peripheral surface in the vicinity of the pore in a porous surface. The multilayer structure includes a dielectric layer having a first part extending on an inner surface of the pore and a second part extending on an outer surface of the peripheral surface; a first coupling layer extending on the first part of the dielectric layer; a first conductive polymer layer extending on the first coupling layer; a second coupling layer extending on at least the second part of the dielectric layer; and a second conductive polymer layer extending on the second coupling layer so that the second conductive polymer layer extends at least over the peripheral surface.
