    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: The present invention provides a multilayer ceramic capacitor in which electrode metal layers and dielectric ceramic layers are laminated alternately and its dielectric constant peak is present at a temperature below −50° C. The multilayer ceramic capacitor is at least one selected from a multilayer ceramic capacitor to be incorporated into an electric circuit in which an electric field of at least 200 V/mm is applied to dielectric layers as a DC bias electric field and an alternating current at a frequency of at least 20 kHz is superimposed and a multilayer ceramic capacitor to be incorporated into an electric circuit in which an electric field of at least 200 V/mm is applied to dielectric layers as an AC electric field. As the dielectric ceramic, a ceramic containing lead atoms whose amount is indicated by being measured in the form of PbO, which is at least 30 mol %, particularly a compound with a perovskite structure represented by ABO3 is used. Thus, an inexpensive large-capacity multilayer capacitor that has thermal resistance and is stable for a high DC bias voltage and a high frequency voltage, and a low loss switching power supply using this capacitor can be provided.
