Publication number: 20120084954Abstract: There is provided a method of manufacturing a solid electrolytic capacitor including: forming a conductive polymer layer on a surface of a metal pellet; and forming a dielectric layer between the metal pellet and the conductive polymer layer. Because the conductive polymer layer is directly formed on the surface of the metal pellet, the conductive polymer layer can be uniformly formed, and because there is no need to form an electrode on the surface of the dielectric layer, the process can be reduced. In addition, because the uniform polymer film is formed irrespective of the size of metal pores and the shape of the capacitor, a capacity of the capacitor can be maximized.Type: ApplicationFiled: October 11, 2011Publication date: April 12, 2012Inventors: Tai Yon Cho, Kwan Hyeong Kim, Jae Bum Cho, Jeong Oh Hong
