Title: Method for manufacturing solid electrolytic capacitor
Inventor: OZAWA MASATO
IPC: H01G9/032
Filed: 2000-03-22
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a solid electrolytic capacitor capable of providing an excellent percentage of capacity achievement and further improving reliability, by suppressing a damage of a dielectric oxide film when a manganese oxide is formed. SOLUTION: The method for manufacturing the solid electrolytic capacitor comprises the steps of dipping an anode 1 formed of a dielectric oxide film layer 2 in a manganese nitrate solution, then dehydrating the anode to form an anhydrous manganese nitrate layer, then dipping the anode 1 in a permanganate aqueous solution, drying then anode 1 to form a manganese dioxide layer, and then forming a conductive polymer layer thereon by an electrolytic polymerization. Thus, a thermal decomposition reaction at a high temperature is eliminated in the formation of the manganese dioxide layer. A damage of the layer 2 is suppressed to reduce a leakage current.  Further, since more manganeses oxide layer is formed to increase an area to be covered, the area to be coated of the conductive polymer due to the later electrolytic polymerization is improved, and the excellent percentage of capacity achievement can be exhibited.
