Patent ID: 8344428

Claim:
An electronic fuse (e-fuse) structure, comprising: a first electrode; a dielectric layer on the first electrode having a plurality of nanochannels therein, wherein each of the nanochannels has a height of from about 20 nanometers to about 100 nanometers; a metal silicide layer that forms an array of metal silicide nanopillars that completely fill each of the nanochannels in the dielectric layer such that the metal silicide layer is present in each of the nanochannels, above each of the nanochannels and over the dielectric layer, each nanopillar in the array serving as an e-fuse element; and a second electrode in direct physical contact with the array of metal silicide nanopillars opposite the first electrode, wherein one of the first electrode and the second electrode serves as an anode of the e-fuse structure and another of the first electrode and the second electrode serves as a cathode of the e-fuse structure.
