  • Fuse structure for maintaining passivation integrity
    Patent number: 7763951
    Abstract: A fuse structure (106) includes a patterned conductor disposed over a passivation layer (302), which is disposed over a substrate (110), such as, for example, an inter-layer dielectric layer of an integrated circuit. A second passivation layer (112) is formed over the integrated circuit including over the fuse structure (106), and then patterned to open a window (108) through the second passivation layer (112) at a location over the fuse structure (106), with the window (108) fully landed by the underlying passivation layer (302). In various aspects of the present invention, the fuse (106) may be programmed either before or after the photoresist layer used in the patterning of the second passivation layer (112) is removed.
