Abstract
To provide a semiconductor device capable of reducing the line width of a fuse. In the semiconductor device, a dummy fuse is provided adjacent to a fuse, each wiring width of the fuse and the dummy fuse is set to the minimum line width, and the interval between the fuse and the dummy fuse is set to the minimum interval. Consequently, the exposure condition of the fuse and the dummy fuse is optimized by OPC, and therefore, it is possible to form the fuse with the minimum line width.
