  • Fuse structure and method for manufacturing it
    Patent number: 5754089
    Abstract: A fuse structure is described in which a metallic frame is inserted between the insulation layers, through which the fuse window passes, and the final passivation layer. This frame is used as a mask during fuse window formation so alignment is simplified and problems arising from the presence of insulating residues on the surface of the fuse window layer are avoided.
    Type: Grant
    Filed: March 24, 1997
    Date of Patent: May 19, 1998
    Assignee: Taiwan Semiconductor Manufacturing Company Ltd.
    Inventors: Der-Cheng Chen, Peng-Cheng Chou
