Abstract:
A method of forming patterns includes the steps of providing a substrate on which a target layer and a hard mask layer are formed; forming a plurality of first resist patterns on the hard mask layer; performing a tilt-angle ion implant process to form a first doped area and a second doped area in the hard mask layer between adjacent first resist patterns; removing the first resist patterns; coating a directed self-assembly (DSA) material layer onto the hard mask layer; performing a self-assembling process of the DSA material layer to form repeatedly arranged block copolymer patterns in the DSA material layer; removing undesired portions from the DSA material layer to form second patterns on the hard mask layer; transferring the second patterns to the hard mask layer to form third patterns; and etching the target layer through the third patterns.

Claim (Index 12):
The method of  claim 10 , wherein forming first doped areas and second doped areas in a hard mask material by a tilt-angle implant process comprises forming the first doped areas and the second doped areas comprising substantially the same width.
