Roll in and Roll out: A Path to High-Throughput Nanoimprint Lithography

Roller-type nanoimprint lithography is a technique that can potentially increase the throughput of the imprinting process to levels competitive for low-cost, large-area, nanoscale manufacturing. A paper in this issue by Ahn and Guo presents a large-area roll-to-roll and roll-to-plate imprint process that builds on earlier work, increasing the substrate width to 4 in. and transferring patterns of 300 nm width and 600 nm pitch at a rate of 1 m/min.
