Abstract
A semiconductor device includes: a logical cell; a spare cell; and a potential fix cell outputting a reference potential used for fixing a potential of an input wiring of the spare cell. The potential fix cell includes: a mutual connection wiring; a first wiring; a second wiring; and an output wiring. The second wiring has a power supply potential, and is wired at a cell boundary between the potential fix cell and an adjacent different cell. The first wiring is wired inside the potential fix cell. The output wiring outputs the reference potential in response to reception of the power supply potential through the second wiring, the mutual connection wiring and the first wiring.
