PROBLEM TO BE SOLVED: To provide a semiconductor device capable of reducing skew by preventing variation in delay time of a signal.SOLUTION: A semiconductor device includes: a first signal line (508) formed by a first wiring layer formed on a semiconductor substrate and disposed in a first direction; first and second shield lines (509, 510) formed by the first wiring layer, disposed on both sides with the first signal line interposed therebetween in the first direction, and to which a first fixed potential is supplied; and a plurality of third shield lines (701) formed by a second wiring layer formed on the semiconductor substrate, disposed so that a part is overlapped with the first signal line and the first and second shield lines at a first wiring width and a first wiring distance in a second direction substantially perpendicular to the first direction, and to which the first fixed potential is supplied. |
