Abstract:
1. A method of manufacturing a semiconductor device, comprising: forming an etched layer on a semiconductor substrate; forming a hard mask pattern including first-directional line pattern units disposed on the etched layer substantially parallel to one another, second-directional line pattern units configured to respectively extend from end portions of the first-directional line pattern units substantially parallel to one another, and contact pad units alternately disposed in the second-directional line pattern units disposed different distances from the end portions of the first-directional line pattern units; and etching the etched layer by performing an etching process using the first hard mask pattern as an etch mask to form a main pattern, the main pattern 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, 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.
