Patent ID: 8379365

Claim:
A capacitor comprising: a first electrode comprising a plurality of first conductive lines and vias, wherein the first conductive lines on the same layer are parallel to each other and connected to a first periphery conductive line, and the first conductor lines aligned in adjacent layers are coupled to each other by the vias, wherein the vias connected to the first conductive lines have a first length parallel to the first conductive lines; a second electrode aligned opposite to the first electrode comprising a plurality of second conductive lines and vias, wherein the second conductive lines on the same layer are parallel to each other and connected to a second periphery conductive line, and the second conductor lines aligned in adjacent layers are coupled to each other by the vias, wherein the vias connected to the second conductive lines have a second length parallel to the second conductive lines and different than the first length; and oxide layers formed between the first electrode and the second electrode, wherein the vias have rectangular shape on a layout.
