Patent ID: 8766452

Claim:
A semiconductor device comprising: a plurality of conductive lines extending in parallel and each comprising a first region extending in a first direction and a second region coupled to the first region and extending in a second direction crossing the first direction; and a plurality of contact pads, each coupled to the second region of a respective one of conductive lines, wherein the plurality of conductive lines are grouped and arranged in a plurality of groups, the first region of a first group is longer than the first region of a second group, and the second region of the first group and the second region of the second group are spaced apart from each other, wherein each of the groups includes first to fourth conductive lines sequentially arranged, and the second regions of the second and third conductive lines have a longer length than the second regions of the first and fourth conductive lines, so that the second regions of the first to fourth conductive lines form a bisymmetric triangle shape.
