摘要:
In a method of forming a pattern structure, a cut-off portion of the node-separated line of a semiconductor device is formed by a double patterning process by using a connection portion of the sacrificial mask pattern and the mask pattern to thereby improve alignment margin. The alignment margin between the mask pattern and the sacrificial mask pattern is increased to an amount of the length of the connection portion of the sacrificial mask pattern. The lines adjacent to the node-separated line include a protrusion portion protruding toward the cut-off portion of the separated line.
