Evaluation of UV roller imprinting using replicated fluorinated film molds

In this study, a fluorinated UV-curable resin was replicated by UV imprinting and used as a film mold. The film mold was fabricated by anti-sticking process (ACP). A remarkable advantage of the application for easy mold fabrication is expected, because it uses only UV imprinting. We evaluated two types of the pattern replications, directions between the stage movement and line and space (L&S) patterns in perpendicular as well as in parallel. The results of replication tests show obvious difference between UV roller imprinting and UV roller press imprinting. In addition, Vickers hardness is measured to evaluate the thermal property of UV roller imprinting. The results indicate that temperature is effective not only to improve pattern replication, but also to accelerate UV curing.
