Development of release agent-free replica mould material for ultraviolet nanoimprinting
NIL is high throughput and low cost to production of high-aspect-ratio nanopatterns. We have therefore developed a hard UV-curable resin with an antifouling effect. It to perform as a release-agent-free replica mould. We carried out repetitive UV-NIL with these replica moulds. We used the error rate as a way of quantifying the deterioration of the replica mould.
