摘要： Multilayered ceramic substrates having Cu electrode patterns in or on ceramic-glass insulating layers which consist essentially of Al.sub.2 O.sub.3, SiO.sub.2, B.sub.2 O.sub.3, Na.sub.2 O, K.sub.2 O, CaO, MgO and PbO. The methods for manufacturing the substrate comprises thermally treating a laminate of alternately superimposing ceramic-glass insulating layers and CuO-based electrode layers of desired patterns in air or in a molecular oxygen-containing atmosphere to eliminate organic binders from the laminates by burning out, reducing the CuO into metallic Cu at low temperatures in an atmosphere containing hydrogen, and firing the thus reduced laminate in an inert gas such as nitrogen. The firing is effected at 850.degree. to 950.degree. C. The multilayered ceramic substrate may also be obtained by forming ceramic-glass insulating layers and CuO-based electrode layers alternately on a sintered ceramic support, followed by the thermal treatment, reduction and firing set forth above.

摘要： A multilayered glass-ceramic substrate using copper as wiring material is fabricated by a step of forming wiring patterns with Au paste for connection of semiconductor chip prepared by adding at least one of Ni powder, Pt powder and Pd powder to Au powder, and copper oxide paste mainly composed of CuO powder, on a green sheet, and burning out the organic pattern by heat treatment in air, a step of reducing the copper oxide electrode by heat treatment in a reducing atmosphere containing hydrogen, and a step of sintering the substrate material, copper oxide electrode and gold electrode by heat treatment in nitrogen. Since the Au wiring pattern is formed on the top layer of the multilayered substrate in this constitution, wire bonding of high reliability is realized. Besides, by making use of the excellent solderability of Au, it may be also applied in flip-chip mounting of semiconductor. In addition, in this Au paste composition, the melting point of Au may be raised, and alloying or fusing is avoided if sintered at 900.degree. C. together with Cu electrode.

摘要： A method of manufacturing a multilayer ceramic using Cu as the conductor material is disclosed. This method comprises a step of forming a multilayer laminate by the green tape multilayer laminating method or by the thick film printing method on ceramic substrate with an insulating material with a mixture of ceramic and glass containing lead oxide as its main component and a conductor paste with CuO as its main component; a step of heat-treatment for decomposing and removing organic binder in air (binder removing process); a step of causing reduction at temperatures where copper oxide is reduced, but lead oxide is not, in a mixed gas atmosphere of nitrogen and hydrogen (reduction process); and a step of firing in a nitrogen atmosphere, thereby effecting sintering of the insulating material composed of ceramic and glass containing lead oxide and metallization of copper electrodes (firing process). For the uppermost layer electrodes, metal copper paste is employed, and a pattern printing process is conducted subsequent to the aforementioned reduction process, so that the sintering of the insulating material and the metallization of the uppermost layer are simultaneously performed; in this way, highly reliable uppermost layer Cu electrodes are obtainable.
