    摘要: A process of producing a multiple-layer glass-ceramic circuit board having a copper conductor, comprising the steps of: forming throughholes in a glass-ceramic green sheet at sites where via-contacts will be formed; filling the throughholes with a powder mixture of a copper powder blended with a ceramic powder, the copper powder and the ceramic powder having a powder particle size providing a packing density comparable with or greater than that of the glass-ceramic green sheet when filled in the throughholes; printing a conductor paste on the green sheet having the throughholes filled with the powder mixture, to form a circuit conductor pattern on the green sheet; laminating a plurality of the green sheets having the conductor pattern formed thereon, to form a laminate body; heating the laminate body to thereby remove a binder therefrom and preliminary-fire the laminate body; and firing the preliminary-fired body.

    摘要: Disclosed is a process for forming a super-conducting film, which a multi-layer metal film (buffer film) is formed at a specific temperature on a ceramic substrate and a superconducting film is formed at a specific temperature on the multi-layer metal film. According to this process, a superconducting film having a high critical temperature can be formed over the ceramic substrate while controlling or suppressing the occurrence of a chemical reaction between the substrate and the superconducting film, and required superconducting performances can be manifested or exhibited.
