Patent ID: 8378447

Claim:
An electrically programmable fuse comprising: an anode; a cathode; a fuse link conductively connecting the cathode with the anode, which is programmable by applying a programming current, the anode and the fuse link each comprising a polysilicon layer and a silicide layer formed on the polysilicon layer, and the cathode comprising the polysilicon layer and a partial silicide layer formed on a predetermined portion of the polysilicon layer of the cathode located adjacent to a cathode junction where the cathode and the fuse link meet, wherein a width of the partial silicide layer of the cathode is a same width as that of the fuse link; and a plurality of contacts formed on the anode and the cathode in a predetermined configuration, wherein at least one contact of the plurality of contacts is formed on the partial silicide layer which is formed on the predetermined portion of the polysilicon layer of the cathode.
