Abstract: An e-fuse device disclosed herein includes an anode and a cathode that are conductively coupled to the doped region formed in a substrate, wherein the anode includes a first metal silicide region positioned on the doped region and a first conductive metal-containing contact that is positioned above and coupled to the first metal silicide region, and the cathode includes a second metal silicide region positioned on the doped region and a second conductive metal-containing contact that is positioned above and conductively coupled to the second metal silicide region. A method disclosed herein includes forming a doped region in a substrate for an e-fuse device and performing at least one common process operation to form a first conductive structure on the doped region of the e-fuse device and a second conductive structure on a source/drain region of a transistor.
