Electrically programmable fuse (eFUSE) using electromigration in silicides

Chandrasekharan Kothandaraman; Sundar K. Iyer; Subramanian S. Iyer

For the first time we describe a positive application of electromigration, as an electrically programmable fuse device (eFUSE). Upon programming, eFUSEs show a large increase in resistance that enable easy sensing. The transient device characteristics show that the eFUSE stays in a low resistance state during programming due to the local heating of the fuse link. The programming is enhanced by a device design that uses a large cathode which increases the temperature gradient and minimizes the effect of microstructural variations.
