چکیده
Nanoimprint lithography, a high-throughput, low-cost, nonconventional lithographic method proposed and demonstrated recently, has been developed and investigated. Nanoimprint lithography has demonstrated 10 nm feature size, 40 nm pitch, vertical and smooth sidewalls, and nearly 90 ° corners. Further experimental study indicates that the ultimate resolution of nanoimprint lithography could be sub-10 nm, the imprint process is repeatable, and the mold is durable. In addition, uniformity over a 15 mm by 18 mm area was demonstrated and the uniformity area can be much larger if a better designed press is used. Nanoimprint lithography over a non-flat surface has also been achieved. Finally, nanoimprint lithography has been successfully used for fabricating nanoscale photodetectors, silicon quantum-dot, quantum-wire, and ring transistors.

Skew angle estimation in document processing using Cohen's class distributions
A skew angle estimation approach based on the application of several time-frequency distributions of Cohen's class to the horizontal projection profile of the page is proposed for document processing. Our results prove that the Wigner-Ville is the best trade-off between accuracy and computational cost. Skew estimation Cohen distributions Document page Projection profile
