Patent ID: 8847411

Claim:
A semiconductor device comprising: a first main pattern including a first line pattern unit configured to extend in a first direction, a third line pattern unit configured to extend from an end portion of the first line pattern unit in a second direction crossing the first direction, and a first contact pad unit formed in the third line pattern unit disposed a first distance from the end portion of the first line pattern unit; a second main pattern including a second line pattern unit configured to extend in the first direction, a fourth line pattern unit configured to extend from an end portion of the second line pattern unit in the second direction, and a second contact pad unit formed in the fourth line pattern unit disposed a second distance from the end portion of the second line pattern unit; and a third main pattern including a fifth line pattern unit configured to extend in the first direction, a sixth line pattern unit configured to extend from an end portion of the fifth line pattern unit in the second direction, and a third contact pad unit formed in the sixth line pattern unit disposed a third distance from the end portion of the fifth line pattern unit, wherein the second distance is different from the first distance, and wherein the first contact pad unit, the second contact pad unit, and third contact pad unit are arranged to zigzag with respect to the third, fourth, and sixth line pattern units.
