Claim Text:
1. A semiconductor device comprising: a plurality of first power supply wirings provided on a first wiring layer and extending in a first direction; a plurality of second power supply wirings provided on a second wiring layer different from the first wiring layer and extending in a second direction intersecting the first direction; a signal wiring provided on the second wiring layer and extending in the second direction; and a plurality of through-hole conductors each electrically connecting an associated one of the first power supply wirings to an associated one of the second power supply wirings; wherein at least a part of the first power supply wirings have a notch in a portion intersecting the signal wiring, and wherein the parasitic capacitance of the signal wiring is reduced, and wherein none of the plurality of through-hole conductors passes through the notch.
