Abstract: The present invention provides a method for producing multilayered ceramic structures having copper-based conductors therein, wherein the onset of sintering of the copper-based conductor can be adjusted to approach or match that of the ceramic portion of the structure. In addition, methods are provided whereby the polymeric binder resin used in formation of the ceramic portion of the structure can be removed or burned-off, using oxygen-containing ambients, wherein the oxygen content is greater than 200 ppm, without oxidation of the copper-based conductors therein.

Abstract: A copper-based paste is disclosed for filling vias in, and forming conductive surface patterns on, ceramic substrate packages for semiconductor chip devices. The paste contains copper aluminate powder in proper particle size and weight proportion to achieve grain size and shrinkage control of the via and thick film copper produced by sintering. The shrinkage of the copper material during sintering is closely matched to that of the ceramic substrate.

Abstract: The cracking experienced during thermal cycling of metal:dielectric semiconductor packages results from a mismatch in thermal co-efficients of expansion. The non-hermeticity associated with such cracking can be addressed by backfilling the permeable cracks (33) with a flexible material (35). Uniform gaps between the metal (32) and dielectric materials (31) can similarly be filled with flexible materials to provide stress relief, bulk compressibility and strength to the package. Furthermore, a permeable, skeletal dielectric can be fabricated as a fired, multilayer structure having sintered metallurgy and subsequently infused with a flexible, temperature-stable material to provide hermeticity and strength.
