  • Patent number: 7923835
    Abstract: An electronic device has a substrate that has first and second peripheral portions. The first peripheral portion provides a shearing position for separation. The electronic device has a plurality of wiring layers one of which forms a functional surface wiring on the substrate, an electronic element mounted on the substrate, and an encapsulation member formed over the substrate and the electronic element. The surface wiring is selectively disposed under the encapsulation member and in an area adjacent to the second peripheral portion.
    Type: Grant
    Filed: January 23, 2008
    Date of Patent: April 12, 2011
    Assignee: Fujitsu Semiconductor Limited
    Inventors: Yoshihiro Kubota, Shirou Youda, Kazuto Tsuji
