Rotation controlled imprinting

Nanoimprint lithography is a potential technology for fabrication of large scale integration systems and nano scale patterning has been reported in many studies. In typical thermal imprint process mold temperature is raised above glass transition temperature (Tg) of the polymer during molding, and cooled down below Tg before de-molding. Step and Stamp Imprint Lithography (SSIL) is a versatile method to pattern various substrate materials by sequential thermal imprinting. In our system, a stamp with size of few millimeters can be used for patterning large areas up to 200 mm. Fabrication of bendable nickel stamps for Roll-to-Roll nanoimprinting and polymer stamps for UV-nanoimprinting has been reported.
