  • Publication number: 20230253297
    Abstract: A semiconductor module includes a supporting substrate, a conductive substrate supported by the supporting substrate, a conductive bonding member provided between the supporting substrate and the conductive substrate, and a semiconductor element electrically bonded to an obverse surface of the conductive substrate and having a switching function. The conductive bonding member includes a metal base layer, a first layer, and a second layer. The first layer is provided between the base layer and the conductive substrate, and is in direct contact with the conductive substrate. The second layer is provided between the base layer and the supporting substrate, and is in direct contact with the supporting substrate.

  • Publication number: 20230245960
    Abstract: A semiconductor module includes a conductive substrate, a plurality of first semiconductor elements, and a plurality of second semiconductor elements. The conductive substrate includes a first conductive portion to which the plurality of first semiconductor elements are electrically bonded, and a second conductive portion to which the plurality of second semiconductor elements are electrically bonded. The semiconductor module further includes a first input terminal, a second input terminal, and a third input terminal that are provided near the first conductive portion. The second input terminal and the third input terminal are spaced apart from each other with the first input terminal therebetween. The first input terminal is electrically connected to the first conductive portion. A polarity of the first input terminal is set to be opposite to a polarity of each of the second input terminal and the third input terminal.

  • Publication number: 20230245961
    Abstract: A semiconductor module includes a conductive substrate, a semiconductor element, a control terminal, and a sealing resin. The conductive substrate has an obverse surface and a reverse surface that are spaced apart from each other in a thickness direction. The semiconductor element is electrically bonded to the obverse surface and has a switching function. The control terminal is configured to control the semiconductor element. The sealing resin has a resin obverse surface and a resin reverse surface, and covers the conductive substrate, the semiconductor element, and a part of the control terminal. The control terminal protrudes from the resin obverse surface, and extends along the thickness direction.

  • Publication number: 20230245956
    Abstract: A semiconductor module includes: a conductive substrate having an obverse surface and a reverse surface spaced apart in a thickness direction; a semiconductor element electrically bonded to the obverse surface and having a switching function; and a conducting member that forms a path of a main circuit current switched by the semiconductor element. The semiconductor element has a rectangular shape with four corners as viewed in the thickness direction. The conducting member includes a portion overlapping with the semiconductor element as viewed in the thickness direction. The conducting member do not overlap with at least three of the four corners of the semiconductor element.
