ABSTRACT:
An architecture of poly fuses includes a number of fuses, a dielectric layer, a sheet-like etching stop layer, and a passivation layer, wherein the sheet-like etching stop layer further includes a number of slices, and wherein each of the slices corresponds to one of the fuses underneath. The architecture of poly fuses according to the invention reduces the energy dispersion during the defective recovering process, and improves the recovery rate for defective memory cells.
