Claim 8:
9. A patterning method, comprising:
obtaining a first imprint template including a line and space pattern formed by a side wall transfer process, the line and space pattern including a first loop end portion at one end and a second loop end portion at another end;
performing an imprint lithography process on a substrate using the first imprint template to transfer the line and space pattern to an imprint resist on the substrate;
after the imprint lithography process, radiation hardening a portion of the imprint resist between the first loop end portion and the second loop end portion;
etching the imprint resist to remove the portions of the imprint resist that were not radiation hardened and leave the portions of the imprint resist that were radiation hardened; and
etching the substrate using the remaining portions of the radiation hardened imprint resist as a mask.
