摘要： Structure providing more reliable fuse blow location, and method of making the same. A vertical metal fuse blow structure has, prior to fuse blow, an intentionally damaged portion of the fuse conductor. The damaged portion helps the fuse blow in a known location, thereby decreasing the resistance variability in post-blow circuits. At the same time, prior to fuse blow, the fuse structure is able to operate normally. The damaged portion of the fuse conductor is made by forming an opening in a cap layer above a portion of the fuse conductor, and etching the fuse conductor. Preferably, the opening is aligned such that the damaged portion is on the top corner of the fuse conductor. A cavity can be formed in the insulator adjacent to the damaged fuse conductor. The damaged fuse structure having a cavity can be easily incorporated in a process of making integrated circuits having air gaps.

摘要： A method of repairing hollow metal void defects in interconnects and resulting structures. After polishing interconnects, hollow metal void defects become visible. The locations of the defects are largely predictable. A repair method patterns a mask material to have openings over the interconnects (and, sometimes, the adjacent dielectric layer) where defects are likely to appear. A local metal cap is formed in the mask openings to repair the defect. A dielectric cap covers the local metal cap and any recesses formed in the adjacent dielectric layer.

摘要： A BEOL e-fuse is disclosed which reliably blows in the via and can be formed even in the tightest pitch BEOL layers. The BEOL e-fuse can be formed utilizing a line first dual damascene process to create a sub-lithographic via to be the programmable link of the e-fuse. The sub-lithographic via can be patterned using standard lithography and the cross section of the via can be tuned to match the target programming current.
