Semiconductor devices having a plurality of fuses and methods of forming the same are provided. The semiconductor device having a fuse including a substrate having a cell region and/or a fuse box region. A first insulation interlayer may be formed on the substrate. A first etch stop layer may be formed on the first insulation interlayer. A metal wiring including a barrier layer, a metal layer and/or a capping layer may be formed on the first etch stop layer of the cell region. Fuses, spaced apart from each other, may be formed on the first etch stop layer of the fuse box region. Each fuse may include the barrier layer and/or the metal layer. A second insulation interlayer having an opening exposing the fuse box region may be formed on the metal wiring and/or the first etch stop layer. The etch stop layer may allow the fuses to be formed more uniformly and decrease the probability of breaking the fuses. |
