Method of manufacturing solid electrolytic capacitor

摘要

A method of manufacturing solid electrolytic capacitors, wherein deposition of electrolyte of a semiconductive metal oxide on a semiconductive dielectric film is performed by electrolytic oxidation from a bath of a metallic salt solution. During the electrolysis, the dielectric film is irradiated by radiation, the energy of which is enough to allow the valence electrons to enter the conduction band, so that due to the thus increased charge carriers the dielectric film more readily conducts electric current.
