Patent ID: 7791111

Claim:
A semiconductor device, comprising: a semiconductor substrate doped with first conductive-type impurities; and a plurality of fuse element portions, each of which include a first fuse interconnect having a fuse portion to be cut, a second fuse interconnect formed separate from the first fuse interconnect and connected to an internal circuit, a first impurity diffusion layer of a second conductive-type formed on a surface of said semiconductor substrate to electrically connect said first fuse interconnect and said second fuse interconnect, and a second impurity diffusion layer of the second conductive-type formed on the surface of said semiconductor substrate and provided separate from said first impurity diffusion layer, wherein said first fuse interconnect, said second fuse interconnect, and said first impurity diffusion layer of each of said plurality of fuse element portions are arranged approximately parallel to one another at a predetermined fuse pitch distance, and wherein each of said fuse element portions has an electro-static protection, said electro-static protection including said first impurity diffusion layer, said second impurity diffusion layer, and said semiconductor substrate.
