A lower interconnect layer is located over the semiconductor substrate, and an upper interconnect layer is located over the lower interconnect layer. A U-shaped lower metal plate is interposed between the lower interconnect layer and the upper interconnect layer. The U-shaped lower metal plate directly contacts the lower interconnect layer. The capacitor dielectric layer covers the inner surface of the lower metal plate. Further, the capacitor dielectric layer has an extension portion interposed between the brim of the lower metal plate and the upper interconnect layer. An upper metal plate covers the inner surface of the capacitor dielectric layer.

    摘要： Methods of forming a thin film by atomic layer deposition are disclosed. These methods generally include the steps of loading a substrate into a reaction chamber, and injecting a first source gas containing a first atom into the reaction chamber to form a chemical adsorption layer containing the first atom on the substrate. In one representative embodiment, a first reaction gas is then injected into the reaction chamber while a first plasma power is applied to the reaction chamber such that the first reaction gas reacts with the chemical adsorption layer containing the first atom to form a first thin film on the substrate. A second source gas containing a second atom is then injected into the reaction chamber to form a chemical adsorption layer containing the second atom on the substrate having the first thin film. A second reaction gas is next injected into the reaction chamber while a second plasma power, which is higher than the first plasma power, is applied to the reaction chamber such that the second reaction gas reacts with the chemical adsorption layer containing the second atom to form a second thin film on the substrate. The first plasma power may be a value selected in a range equal to or greater than 0 W and less than about 500 W, and the second plasma power may be a value selected in a range greater than the first plasma power and less than about 2000 W. A thickness of the second thin film may be equal to or greater than a thickness of the first thin film.
