Claim:
1. A non-continuous line pattern structure on a semiconductor integrated circuit (IC) substrate, comprising: a plurality of first line pattern segments parallel to a first direction disposed on the semiconductor IC substrate, any two adjacent first line pattern segments of the first line pattern segments having a first line spacing disposed between the two adjacent first line pattern segments, wherein the first line pattern segments are composed of a plurality of first polymer structures respectively; and a plurality of second line pattern segments parallel to the first direction disposed on the semiconductor IC substrate, any two adjacent second line pattern segments of the second line pattern segments having a second line spacing disposed between the two adjacent second line pattern segments, wherein the second line pattern segments are composed of a plurality of second polymer structures respectively, wherein the first polymer structures and the second polymer structures comprise directed self-assembly (DSA) material, the first line pattern segments and the second line pattern segments are arranged alternately along a second direction perpendicular to the first direction, and the first line pattern segments and the second line pattern segments are not overlapped with each other along the second direction and are not connected to each other.
