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 15):
The method of  claim 10 , wherein self-assembling the DSA material to form first block copolymer patterns and second block copolymer patterns comprises forming the first block copolymer patterns over the undoped areas and forming the second block copolymer patterns over the first doped areas and the second doped areas.
