NON-LEAD DIELECTRIC THIN FILM, COMPOSITION FOR FORMING THIS FILM, AND METHOD FOR FORMING THIS FILM

摘要

PROBLEM TO BE SOLVED: To provide a non-lead dielectric thin film free from lead, and having high crystal orientation and high relative dielectric constant.SOLUTION: A non-lead dielectric thin film is controlled in (111) orientation by including at least two components of a component of BaTiO, a component of Bi(MgTi)Oand a component of BiFeO, or controlled in (100) orientation by including at least two components of a component of BaTiO, a component of Bi(MgTi)Oand a component of BiFeO. The non-lead dielectric thin film is formed on (111)SrRuOor on (100)LaNiO.
