摘要：
A fabrication method for fabricating an electrically programmable fuse method includes depositing a polysilicon layer on a substrate, patterning an anode contact region, a cathode contact region and a fuse link conductively connecting the cathode contact region with the anode contact region, which is programmable by applying a programming current, depositing a silicide layer on the polysilicon layer, and forming a plurality of anisometric contacts on the silicide layer of the cathode contact region and the anode contact region in a predetermined configuration, respectively.
