    摘要: A multilayer ceramic substrate comprising at least one ceramic layer made by laminating at least one ceramic green sheet layer and conductor layers formed on surfaces of the at least one ceramic green sheet layer into laminates and by sintering the resulting laminates. Each ceramic green sheet layer comprises a ceramic precursor composition comprising (I) 100 parts by weight of ceramic fine powder having an average particle diameter of 10 microns or less as component (C) and (II) 5 to 30 parts by weight, based on 100 parts by weight of the ceramic fine powder, of an organic binder for bonding the ceramic fine powder. The organic binder comprises (i) 100 parts by weight of a water insoluble polymer of at least one vinyl monomer as a major component of the organic binder, as component (A), and (ii) 1 to 9.5 parts by weight, based on 100 parts by weight of the component (A), of water soluble polymer as component (B). In the binder particles of the component (A) being dispersed by the component (B) in an aqueous medium resulting from suspension polymerization of the at least one vinyl monomer in water containing the water soluble polymer as a dispersion stabilizer.

    摘要: According to this method for manufacturing a multilayer glass-ceramic circuit board, a green sheet laminate is fired in a non-oxidizing atmosphere in a first firing step so that a void content of at least 10% is maintained and strength of the ceramic laminate is increased. Then the laminate is fired in an oxidizing atmosphere in a second firing step so that the organic binder contained in the laminate is removed and the residual carbon content is at most 200 ppm. Thereafter the laminate is fired in a reducing atmosphere in a third firing step to reduce the oxidized conductor circuit. Finally, the laminate is fired in a non-oxidizing atmosphere in a fourth firing step to densify the ceramic laminate. The firing temperature in the first, second and third steps is 100.degree.-200.degree. C. lower than the softening point of the glass and the firing temperature in the fourth step is higher than the softening point of the glass and lower than the melting point of the conductor.
