Damascene anti-fuse with slot via

摘要

Interconnect structures comprising a substrate having a first level of electrically conductive features formed thereon; a patterned interlevel dielectric material formed on said substrate, wherein said patterned interlevel dielectric includes via spaces, wherein at least one of said via spaces is a slot via in which an anti-fuse material is formed on a portion thereof; and a second level of electrically conductive features formed in said spaces, whereby the anti-fuse material in the slot via provides a connection between the first and second levels of electrically conductive features and a method of fabricating the same.
