Patent ID: 8258574

Claim:
A semiconductor device, comprising: a plurality of decoupling capacitors disposed on a semiconductor substrate; and a plurality of decoupling capacitor contact plugs disposed between the semiconductor substrate and the plurality of decoupling capacitors, the plurality of decoupling capacitor contact plugs being electrically connected to the plurality of decoupling capacitors and including an array of first decoupling capacitor contact plugs and second decoupling capacitor contact plugs, wherein: the first decoupling capacitor contact plugs are repeatedly arranged along a first direction at a predetermined distance apart from each other, the second decoupling capacitor contact plugs are spaced at a predetermined distance from the first decoupling capacitor contact plugs in a second direction, which is different from the first direction, and are repeatedly arranged along the first direction at predetermined distance apart from each other, and the plurality of decoupling capacitor contact plugs are isolated from each other by interlayer insulation layers disposed therebetween, the interlayer insulation layers being in spaces between the decoupling capacitor contact plugs such that the interlayer insulation layers are connected to each other in the second direction, thereby improving mechanical strength thereof.
