ACW offers PFAS-free working stamp resins for both micro- and nano-imprint lithography applications. These materials offer the following advantages:
- PFAS-free, environmentally friendly and not restricted
- No anti-stick layer on the working stamp required in the imprint step, thus reducing process steps
- Excellent chemical resistance, resists etching from aggressive imprint resins and minimizes height gain in multiple imprints
- excellent mechanical and thermal stability for multiple imprints
ACW offers both acrylate and epoxy working stamp resins, and they are designed for both hard stamps (glass backplane) for micro-imprinting and soft stamps (PET backplane) for nano-imprinting.
