Patent ID: 7915647

Claim:
A semiconductor integrated circuit comprising: a cell array composed of a plurality of blocks in which a plurality of elements are arrayed; a plurality of conducting wires extending from the cell array to a lead area; and a plurality of contact holes arranged in the lead area so that a distance from the end of the cell array sequentially increases from one to the other of the plurality of conducting wires, each of the plurality of conducting wires having: a first conducting wire portion; a second conducting wire portion connected to the contact hole; and a third conducting wire portion electrically connecting the first conducting wire portion to the second conducting wire portion, a width of the third conducting wire portion gradually decreasing from a side of the first conducting wire portion toward a side of the second conducting wire portion, wherein an end portion of the first conducting wire portion which contacts to the third conducting wire portion extends with a first conducting wire width, and the second conducting wire portion has a second conducting wire width smaller than the first conducting wire width, and wherein central points of the plurality of contact holes are shifted with respect to central lines of the plurality of conducting wires toward a side of conducting wires where lengths of the plurality of conducting wires extending at one end from the end of the cell array are shorter.
