Photo-curable resists for inkjet dispensing applied in large area and high throughput roll-to-roll nanoimprint processes
R2R-NIL is presented with high throughput roller speeds of 30mmin?1 and good pattern fidelity. The viscosity of the novel materials is below 20mPas, enabling inkjet dispensing at room temperature. Throughput variation from 1mmin?1 to 20mmin?1 decreased double bond conversion less than 5%.
