Abstract
Wirings connected to a gate electrode of a slave switch circuit cell for substrate bias circuits are respectively electrically connected to a wiring for a power supply potential and a wiring for a reference potential. Thus, the switch operation of the slave switch circuit cell is made invalid. Wirings connected to n wells of respective circuit cells are electrically connected to a wiring for the power supply potential, and wirings connected to p wells of the respective circuit cells are electrically connected to the wiring. Thus, the n wells are fixed to the power supply potential, and the p wells are fixed to the reference potential.
