Patent ID: 7786585

Claim:
A semiconductor integrated circuit device comprising: a first insulating film formed over a semiconductor substrate; first and third grooves formed in the first insulating film and extending in a first direction; a first wiring and a third wiring which are formed of a first conductive film buried in the first and third grooves, respectively; a second insulating film formed over the first insulating film, the first wiring and the third wiring; a third insulating film formed over the second insulating film; a second groove formed in the third insulating film and extending in a second direction, perpendicular to the first direction; a first hole and a second hole formed in the second insulating film, respectively, wherein the first hole is connected with the first wiring and the second groove, and wherein the second hole is connected with the third wiring and the second groove; and a second wiring, a first plug and a second plug which are formed of a second conductive film buried in the second groove, the first hole and the second hole, respectively; wherein the first conductive film and the second conductive film are formed of copper as a main component, wherein, in the second direction, the first wiring has a first end near the third wiring, and a second end distant from the third wiring, wherein, in the second direction, the first plug is arranged so that the distance from the center of the first plug to the first end of the first wiring differs from the distance from the center of the first plug to the second end of the first wiring, wherein, in the second direction, the third wiring has a first end near the first wiring, and a second end distant from the first wiring, wherein, in the second direction, the second plug is arranged so that the distance from the center of the second plug to the first end of the third wiring differs from the distance from the center of the second plug to the second end of the third wiring, wherein, in the second direction, the first plug is arranged near the first end of the first wiring, and wherein, in the second direction, the second plug is arranged near the first end of the third wiring.
