    Abstract: A first insulating layer is formed on first wiring and thereafter an etching resistant film is formed thereon. A lower layer portion of a second insulating layer is formed on the etching resistant film. Upon etching for forming dummy trenches, the rate of etching of the etching resistant film is less than or equal to one-tenth the rate of etching of the insulating layer. Therefore, the etching resistant film functions as an etching stopper and the etching thereof does not proceed to the first insulating layer. Thus, the interval between the corresponding first wiring and a second wiring can be reliably maintained and an increase in parasitic capacitance is hence prevented. An insulator lying within a wiring section is made unnecessary while a dishing phenomenon is prevented, by bottom-up filling of a copper-plated film due to the dummy trenches. Thus, wiring resistance is prevented from increasing.

    Abstract: A thin film dielectric device is disclosed, that comprises a substrate, a lower electrode formed on the substrate and composed of a laminate film having columnar grains that have grown in a vertical to a surface of the substrate, a dielectric thin film formed on the lower electrode and composed of a perovskite oxide, the dielectric thin film being a polycrystalline film having columnar grains that have successively grown from the columnar grains of the lower electrode and that takes over a crystal orientation of the lower electrode, the lattice constant of the lower electrode being matched with the lattice constant of the dielectric thin film at the interface therebetween with the columnar grains, and an upper electrode formed on the dielectric thin film. The lattice matching of the columnar grains solves problems of the increase of the leak current of the thin film dielectric device and the degradation of the dielectric breakdown resistance. In addition, the polycrystalline film having the columnar grains that succeed at the interface of the electrode/dielectric thin film can be properly formed on the semiconductor substrate such as Si substrate. Thus, the thin film dielectric device according to the present invention can be applied to a real LSI circuit and so forth.
