Abstract:
1. An electrically programmable fuse comprising: an anode contact region and a cathode contact region formed from a polysilicon layer having a silicide layer formed thereon; a fuse link conductively connecting the cathode contact region with the anode contact region, which is programmable by applying a programming current; and a plurality of anisometric contacts formed on the silicide layer of the cathode contact region and the anode contact region in a predetermined configuration, respectively, wherein a width of the anode and cathode contact regions is less than a length of each anisometric contact in a longitudinal direction of the electrically programmable fuse, and wherein the width of the anode and cathode contact regions refers to a dimension perpendicular to the longitudinal direction and also parallel to a plane of the substrate.
