摘要:
The cost of a semiconductor device is to be reduced. An electrical connection between a first semiconductor chip and a second semiconductor chip stacked on the first semiconductor chip is made through an inner lead portion of a lead disposed at a position around the first semiconductor chip and two bonding wires.

An electric circuit board module includes a substrate with electric components mounted on one side thereof and electrodes provided on the other side thereof for the electric connection with the mounted electrical components. The electric circuit board module further includes conductor columns adhered to the electrodes and an adhesion layer provided on the other side of the substrate and around the conductor columns such that the conductor columns extrude from the adhesion layer by a predetermined length. By pressing the electric circuit board module against a separate circuit board to mount thereon, the electric components are electrically connected with electrodes of the sperate circuit board through conductor columns. Since conductor columns are made of a resinous paste with metallic powders dispersed therein, no heating operation as required in conventional module using a solder flow is necessary, resulting in that electric components are kept from the degradation caused by the heat.
摘要:
A manufacturing method for a multilayered ceramic body using Cu, Ni, Co or Fe as a conductor material, and a conductor forming paste of a particular composition of CuO, NiO, CoO or Fe.sub.2 O.sub.3 as the main component, the paste being applied to the multilayered body. The manufacturing method comprises: a process of forming the multilayered body with conductor paste of CuO, NiO, CoO or Fe.sub.2 O.sub.3 as the main component and insulating paste formed of glass and/or ceramic, so that a binder is removed from the laminate by heat treatment in an oxidizing atmosphere; a process of heat treatment for reducing the oxide; and a sintering process for sintering the laminate in a nitrogen atmosphere.
摘要:
A thick film conductor composition for a ceramic wiring substrate comprises an inorganic ingredient mainly composed of a copper oxide powder added with a metal capable of forming a homogeneous solid solution with copper, and an organic vehicle. The inorganic ingredient may be further added with a manganese oxide or a heat resistant insulating material such as ceramics and/or glass.

A machine translation device includes: an accepting portion that accepts a first-language document; storage portion in which are stored one or more pieces of multilingual parallel translation information that are each a set of synonymous words in the first language through the Nth language (N is 3 or more integer); a selecting portion that selects the multilingual parallel translation information including a word included in an ith-language document (i is an integer of 1 to N-1) from the one or more pieces of multilingual parallel translation information; a machine translation portion that repeats processing of machine translating the ith-language document into an (i+1)th language document until machine translation into the Nth language has been performed, so as to use parallel-translation relation between two languages included in the selected multilingual parallel translation information; and an output portion that outputs the Nth-language document.
摘要:
A substrate provided with conductive terminals and another substrate provided with electrode pads and two-stepped electrical contact bumps formed respectively on the electrode pads and each consisting of a first raised portion and a second raised portion formed on the first raised portion, are joined securely by bonding the second raised portions coated respectively with droplets of conductive adhesive and the corresponding conductive terminals by the droplets of the conductive adhesive. The ratio of the area of a section of the first raised portion in a plane parallel to the surface of the electrode pad is greater than the area of a section of the second raised portion parallel to the section of the first raised portion at a predetermined ratio. In an exemplary method of forming the electrical contact bump, the second raised portion is formed by bending a conductive wire in a loop by a ball bonding apparatus.
