  • Solution raw material for forming composite oxide type dielectric thin film and dielectric thin film
    Patent number: 6485554
    Abstract: The present invention provides a solution suitable for forming a composite oxide type dielectric thin film containing at least one organometallic compound dissolved in at least one solvent selected from the group consisting of cyclic or acyclic diethers, alkyl-substituted cyclic monoethers, mono- or di-branched alkyl monoethers, alkoxy alcohols, diols, and acetoacetic esters, or dissolved in a solvent mixture comprising at least one solvent selected from the group consisting of cyclic and acyclic saturated hydrocarbons, and at least one solvent selected from the group consisting of cyclic or acyclic diethers, alkyl-substituted cyclic monoethers, mono- or di-branched alkyl monoethers, alkoxy alcohols, diols, acetoacetic esters, and unsubstituted or alkyl-substituted pyridine.
