Abstract
A fuse for semiconductor devices, in accordance with the present invention, includes a cathode formed from a first material, an anode formed from a second material and a fuse link connecting the cathode and the anode and formed from the second material. The second material is more susceptible to material migration than the first material when the fuse is electrically active such that material migration is enhanced in the second material.
