Abstract:
1. A method, comprising: patterning a first substrate using an imprint lithography template, the imprint lithography template having a first feature pattern having a first plurality of protrusions and recessions; in response to patterning the first substrate, forming, in the first substrate, a first replica having a second feature pattern having a second plurality of protrusions and recessions, the second feature pattern being a mirror image of the first feature pattern; patterning a second substrate using the first replica; and in response to patterning the second substrate, forming, in the second substrate, a second replica having i) a body, ii) raised edges extending from only a portion of the body defining a mesa therebetween and iii) a third feature pattern formed on the mesa and having a third plurality of protrusions and recessions, wherein the first feature pattern and the third feature pattern are substantially similar.
