摘要：
A method of patterning a substrate, comprises patterning a photoresist layer disposed on the substrate using imprint lithography and etching exposed portions of a hard mask layer disposed between the patterned photoresist layer and the substrate. The method may also comprise implanting ions into a magnetic layer in the substrate while the etched hard mask layer is disposed thereon.
