Abstract: A multilayered ceramic (MLC) substrate having embedded and exposed conductors suitable for mounting and interconnecting a plurality of electronic devices exterior thereof. The horizontal planar conductors comprise substantially a plurality of solid, non porous, homogeneous metal patterns (26), whereas the vertical interplanar connection conductors (26A) are substantially porous metal conductors that are formed by methods such as screening. The process to form the MLC substrate involves forming a pattern of solid, nonporous conductors to a backing sheet (24) having a release layer, then transferring the pattern to a ceramic green sheet (22). Zero X-Y shrinkage sintering processes allow the MLC substrate and solid metal conductors to be densified without distortion of the solid metal patterns or the ceramic.

Abstract: Production of a sintered ceramic dielectric formed from a green sheet having a uniform microporous structure providing uniform dielectric properties and compressibility for lamination of stacked green sheets into a unitary laminate which may be provided with an internal pattern of electrical conductors extending therein. The structure is obtained by blending the ceramic particulate with a binder resin soluble in an azeotropic mixture which is formed from a solvent for the binder resin and a non-solvent in which the resin is at most only slightly soluble, which on evaporation of said azeotropic mixture forms said structure.
