Patent ID: 8093723

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 to a first direction; first and third wirings comprised of a first conductive film and buried in the first and third grooves, respectively, a width, in a second direction perpendicular to the first direction, of the first wiring being greater than a width, in the second direction, of the third wiring; a second insulating film formed over the first insulating film, the first wiring and the third wiring; a second groove formed in the second insulating film and extending to the second direction; first and second holes formed in the second insulating film such that the first hole is connected with the first wiring and the second groove and such that the second hole is connected with the third wiring and the second groove; and a second wiring, a first plug and a second plug comprised of a second conductive film and buried in the second groove, the first holes and the second hole, respectively, a width, in the second direction, of the first wiring being greater than a width, in the first direction, of the second wiring such that the second wiring has a width, in the first direction, which prevents the forming of two first plugs adjacent to each other in the first direction, wherein the first conductive film and the second conductive film are comprised of copper as a main component, respectively, 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.
