Abstract:
1. An imprint lithography method comprising: providing a substrate having (i) a first amount of imprintable medium for nanoimprint lithography on a first area of the substrate, the first amount of imprintable medium, when fixed, having a first etch rate as a physical characteristic thereof, and having (ii) a second amount of imprintable medium for nanoimprint lithography on a second area of the substrate different from the first area of the substrate, the second amount of imprintable medium, when fixed, having a second etch rate as a physical characteristic thereof, wherein the second etch rate is different from the first etch rate; and imprinting at least part of an imprint template into both the first amount of imprintable medium and the second amount of imprintable medium when both the first and second amounts are on the substrate substantially at a same time.
