| 20100118468 | Thin Film Capacitor and Manufacturing Method Therefor - A thin film capacitor including a substrate, a capacitor portion having an upper conductor, a lower conductor, and a dielectric thin film, and a resin protective layer for protecting the capacitor portion. A barrier layer is interposed between the capacitor portion and the resin protective layer. The barrier layer includes a crystalline dielectric barrier layer formed in contact with the capacitor portion and having the same composition system as the dielectric thin film, and an amorphous inorganic barrier layer formed on the surface of the crystalline dielectric barrier layer and composed of silicon nitride having non-conductivity. The inorganic barrier layer prevents deterioration in the properties of the dielectric thin film by blocking diffusion of the constituent elements of the inorganic barrier layer toward the capacitor portion. | 05-13-2010 |
