  • Apparatus for selectively cutting fuse electrodes
    Patent number: 6822309
    Abstract: Adjacent ones of a plurality of fuse electrodes extending parallel to each other are cut off by a laser beam. Cutting positions on the adjacent fuse electrodes are set to positions which are different from each other in a direction in which the fuse electrodes extend. Since the cutting positions on the adjacent fuse electrodes are different from each other, the adjacent fuse electrodes are prevented from being short-circuited by fragments of components thereof that are scattered when the laser beam is applied to cut off the fuse electrodes.
    Type: Grant
    Filed: March 22, 2001
    Date of Patent: November 23, 2004
    Assignee: NEC Electronics Corporation
    Inventor: Tomoki Hirota
