Patent ID: 7750472

Claim:
A device comprising: a plurality of contact plugs formed in an interlayer dielectric covering a silicon substrate, each contact plug configured to be in electrical contact with an active area of the silicon substrate; a first aluminum interconnection formed over a first contact plug and having a width larger than a width of the first contact plug; a dielectric covering an upper surface and a side surface of the first aluminum interconnection; a second aluminum interconnection formed over a second contact plug adjacent to the first contact plug, and further formed over at least a portion of the first aluminum interconnection, insulated from the first aluminum interconnection by the dielectric, and having a width larger than a width of the second contact plug; a plurality of first aluminum interconnections formed over a plurality of first alternating contact plugs, wherein one first aluminum interconnection is formed for every two alternating contact plugs; and a plurality of second aluminum interconnections formed over a plurality of second alternating contact plugs, each of the plurality of first alternating contact plugs being between each of the plurality of second alternating contact plugs in an alternating pattern.
