Instead of the

• technique, which was developed by Philips Research and SUSS MicroTec, combines the advantages of both UV nanoimprint lithography techniques with rigid stamp for the best resolution and with soft stamp for the large-area (6 inch area) patterning. Thermal oxide several nanometers thick was grown on the pre
