    摘要: An e-fuse structure and method has anode, a fuse link, and a cathode. The first end of the fuse link is connected to the anode and the second end of the fuse link opposite the first end is connected to the cathode. This structure also includes a first silicide layer on the anode and the fuse link and a second silicide layer, different than the first silicide layer, on the cathode. The difference between the first silicide layer and the second silicide layer causes an enhanced flux divergence region at the second end of the fuse link.

    摘要: An e-fuse structure and method has an anode; a fuse link (a first end of the fuse link is connected to the anode); a cathode (a second end of the fuse link opposite the first end is connected to the cathode); and a silicide layer on the fuse link. The silicide layer has a first silicide region adjacent the anode and a second silicide region adjacent the cathode. The second silicide region comprises an impurity not contained within the first silicide region. Further, the first silicide region is thinner than the second silicide region.
