    摘要: A thin film capacitor including a first electrode having on its surface a (100) face of cubic system or a (001) face of tetragonal system, a dielectric thin film epitaxially grown on the first electrode and exhibiting a crystal structure which inherently belongs to a perovskite structure of cubic system, and a second electrode formed on the dielectric thin film. Further, the dielectric thin film meets the following relationship V/V.sub.0 .gtoreq.1.01 where a unit lattice volume of true perovskite crystal structure belonging to the cubic system (lattice constant a.sub.0) is represented by V.sub.0 =a.sub.0.sup.3, and a unit lattice volume (lattice constant a=b.noteq.c) which is strained toward a tetragonal system after the epitaxial growth is represented by V=a.sup.2 c, and also meets the following relationship c/a.gtoreq.1.01 where c/a represents a ratio between a lattice constant "c" in the direction thicknesswise of the film and a lattice constant "a" in the direction parallel with a plane of the film.

    摘要: 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.

    摘要: In an embodiment of the present invention, a semiconductor layer having regions into which a p-type impurity, an n-type impurity and a (p+n) impurity are respectively introduced is formed as a surface layer by being heat-treated. An impurity segregation layer on these regions is removed, and a film of a metallic material is thereafter formed on the regions and is heat-treated, thereby forming a silicide film on the semiconductor layer. In another embodiment, an impurity is introduced into the impurity segregation layer, and a film of a metallic material is thereafter formed on the impurity segregation layer and is heat-treated to form a silicide film.
