    摘要: The capacitor according to the present invention comprises a lower electrode 18 formed on a base substrate 14, a dielectric film 20 formed on the lower electrode 18, and an upper electrode 28 formed on the dielectric film 20 and including a polycrystalline conduction film 22, and a amorphous conduction film 24 formed on the polycrystalline conduction film 22. Because of the amorphous conduction film 24 included in the upper electrode 28, which can shut off hydrogen and water, hydrogen and water can be prohibited from arriving at the dielectric film 20. Accordingly, the dielectric film 20 of an oxide is prevented from being reduced with hydrogen, and the capacitor can have good electric characteristics.
