Abstract
A capacitor having a perovskite series dielectric film, and manufacturing method thereof are provided. The perovskite series dielectric film capacitor is characterized in that the perovskite series dielectric film contains copper. The method of manufacturing the perovskite series dielectric film which contains copper includes forming the perovskite series dielectric film on a lower electrode, forming a Cu O film on the perovskite series dielectric film, and permitting Cu O or copper of the Cu O film to penetrate the perovskite series dielectric film preferably by a heat treatment. In the perovskite series dielectric film capacitor, Cu O or copper penetrates the grain boundary of the perovskite series dielectric film having a columnar crystal structure, thereby improving a leakage current characteristic of the perovskite series dielectric film.
