Filed: 1996-07-02
Abstract: PROBLEM TO BE SOLVED: To produce the multilayer thin film consisting of the substances oriented to the direction of a specific plane, in the production of a multilayer thin film consisting of a combination of at least two substances each of which has lattice constants greatly different from those of the other and accordingly, the epitaxial growth of which on a nonoriented substrate is impossible. SOLUTION: In this production, a multilayer thin film consisting of a combination of at least two substances each of which has >=2% lattice mismatch to the other is formed on a nonoriented substrate while irradiating the surface of the substrate with an ion beam, a laser beam or X-rays at an irradiation angle in the range of 30 to 60 deg.. Thus, the objective multilayer thin film which is oriented to the direction of a specific plane to enable attainment of a reduction in electric field resistance, is produced. For example, the surface of an Si substrate 11 is oxidized to form a layer of SiO2 12 on the surface of the Si substrate 11 and then, a barrier layer of TiN 13 is formed on the layer of SiO2 12 to form a base substrate consisting of the Si substrate 11 and the layers of SiO2 12 and TiN 13. Thereafter, Au is sputtered to deposit it on the base substrate while irradiating the surface of the base substrate with an ion beam at an irradiation angle adjusted to 45 deg. to form an Au film used as a lower electrode 14 on the base substrate. Then, a (Ba0.5 Sr0.5 )TiO3 thin film used as a high-dielectric material 15 is formed on the lower electrode 14 by sputtering. Finally, similarly to the formation of the lower electrode 14, an Au film used as an upper electrode 16 is formed on the high-dielectric material 15.
