  • Patent number: 10770400
    Abstract: A semiconductor module includes a substrate, two bare chips (semiconductor elements) mounted on the substrate, and a case fixed to the substrate. A conductor pattern and five signal patterns are provided for each bare chip on an upper surface of an insulating substrate. Signal electrodes and the signal patterns of the bare chips are connected to by conductive plates. An insulating member is provided on connecting portions of the conductive plates.
    Type: Grant

  • Patent number: 10049978
    Abstract: A semiconductor module includes a wiring substrate and two semiconductor devices mounted on the wiring substrate. The semiconductor module includes a housing having a rectangular frame body including four side walls. The housing includes a beam that bridges first side walls. A bus bar includes two end portions, upright portions each extending from one of the end portions in the thickness direction of an insulating substrate, bent portions each extending continuously with one of the upright portions, and an extension extending continuously with the bent portions. A section of the extension is embedded in the housing.

  • Patent number: 9332638
    Abstract: An electrically conductive path is configured from a first copper plate, a second copper plate, and solder. The first copper plate has a first bent section extended from a first joining section joined to an electrically insulative board and bent toward the rear surface of the electrically insulative board. The second copper plate has a second bent section which is extended from a second joining section joined to the electrically insulative board, is bent toward the front surface of the electrically insulative board, and is disposed so as to cover, together with the first bent section, the inner wall surface of a base-material through-hole. Through-holes are provided in the portions of the second copper plate which face the inside of the base-material through-hole. Solder is filled between the first bent section and the second bent section.
