Patent ID: 7274085

Claim:
A capacitor structure, comprising: a first layer conductive pattern comprising: a first closed conductive ring; a plurality of first major conductive bars arranged in parallel and electrically connected to the first closed conductive ring; and a plurality of first minor conductive bars arranged alternately with the first major conductive bars and not electrically connected to the first closed conductive ring; a second layer conductive pattern disposed above the first layer conductive pattern, the second layer conductive pattern comprising; a second closed conductive ring; a plurality of second major conductive bars arranged in parallel and electrically connected to the second closed conductive ring; and a plurality of second minor conductive bars arranged alternately with the second major conductive bars and not electrically connected to the second closed conductive ring; a dielectric layer sandwiched between the first layer conductive pattern and the second layer conductive pattern; and a plurality of contact plugs disposed in the dielectric layer, comprising a plurality of first contact plugs and a plurality of second contact plugs, wherein each of the first minor conductive bars is electrically connected to the second major conductive bars through at least two of the first contact plugs, and each of the second minor conductive bars is electrically connected to the first major conductive bars through at least two of the second contact plugs.
