  • Patent number: 9035438
    Abstract: The present specification relates to a semiconductor device in which a metal plate is attached onto a surface of a resin package, and provides a structure in which the metal plate is not easy to separate. The semiconductor device disclosed in the present specification includes semiconductor chips (IGBT, diode), a resin package molding the semiconductor chips, and metal plates fixed onto the surface of the resin package. An anchoring member is bridged between two points on a back face of the metal plate. A space between one of the metal plates and the anchoring member is filled with a molding resin of the resin package. The anchoring member firmly bites the resin package, and therefore, the metal plate is difficult to be released from the resin package.

  • Publication number: 20150123241
    Abstract: An integrated heat sink array is introduced in SOI power devices having multiple unit cells, which can be used to reduce the temperature rise in obtaining more uniform temperature peaks for all the unit cells across the device area, so that the hot spot which is prone to breakdown can be avoided, thus the safe operating area of the device can be improved. Also the array sacrifice less area of the device, therefore results in low Rdson.
