1. A semiconductor device, comprising:
a plurality of circuits that are provided on a semiconductor substrate, and that each include a semiconductor element having a threshold voltage, the threshold voltage controlled by a substrate voltage supplied to the semiconductor substrate; a mesh-patterned first wiring that supplies each of the plurality of circuits with a power source voltage supplied to a plurality of locations at an outer periphery of the first wiring; a mesh-patterned second wiring that is provided at a wiring layer, and that receives a supply of the substrate voltage; and a mesh-patterned third wiring that is provided at a different wiring layer from the wiring layer at which the second wiring is provided, that has an outer periphery connected to an outer periphery of the second wiring, and that supplies the substrate voltage to the semiconductor substrate. |
