Patent ID: 7936001

Claim:
A semiconductor device, comprising: a first interlayer insulating film provided above a semiconductor substrate; a second interlayer insulating film, provided above said first interlayer insulating film, and having a larger thickness than the thickness of said first interlayer insulating film; and a pair of adjacent electroconductive connecting plugs, provided to cover from said first interlayer insulating film to said second interlayer insulating film, and extending through said first interlayer insulating film and said second interlayer insulating film, wherein each of said pair of adjacent electroconductive connecting plugs includes an electroconductive first plug extending through said first interlayer insulating film and an electroconductive second plug extending through said second interlayer insulating film and being coupled to said electroconductive first plug, wherein said electroconductive first plugs and said electroconductive second plugs are arranged in said pair of adjacent electroconductive connecting plugs so that a center-to-center distance of said electroconductive second plugs is larger than a center-to-center distance of said electroconductive first plugs along both a first direction and a second direction perpendicular to the first direction, and wherein the electroconductive first and second plugs have tapered geometries, said electroconductive first plugs connected to a gate electrode are parallel to each other, and said first direction is parallel to said gate electrode.
