Abstract
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.
