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 14):
A method of patterning a target material, comprising:\n forming a resist pattern comprising a first width and a first pitch; exposing a hard mask material under the resist pattern to a tilt-angle ion implant process through the resist pattern to form first doped areas and second doped areas in the hard mask material; removing the resist pattern; forming a directed self-assembly (DSA) material comprising a first block copolymer and a second block copolymer on the hard mask material; self-assembling the DSA material to form a first block copolymer pattern and a second block copolymer pattern on the hard mask material; removing the first block copolymer pattern or the second block copolymer pattern to form a DSA material pattern on the hard mask material, the DSA material pattern comprising a second pitch smaller than the first pitch; removing the hard mask material exposed through the DSA material pattern to form a hard mask pattern; and removing a target material exposed through the hard mask pattern to form a target material pattern, the target material pattern comprising the second pitch.
