  • Publication number: 20020119622
    Abstract: The present invention provides a method of manufacturing a capacitor on a semiconductor wafer. The method comprises placing a metal nitride film, such as a tantalum nitride film, on a substrate of a semiconductor wafer. A first electrode and a dielectric layer are created from the metal nitride film by subjecting the metal nitride film to a plasma oxidation process, which forms a blended interface between the first electrode and the dielectric layer. To complete the capacitor, a second electrode is formed over the dielectric. Interconnections with other semiconductor devices may also be formed on the wafer to create an operative integrated circuit.
