Abstract
A semiconductor integrated circuit device in which a wiring layer which supplies a predetermined operation voltage to an electronic circuit has a decreased parasitic impedance. The wiring layer is constituted by a first path and a second path that are connected in parallel between a connection pad and the electronic circuit, or a second wiring layer that constitutes an AC loop is formed close to the first wiring layer which supplies the operation voltage, or the above-mentioned two structures are employed in combination.
