Abstract:
1. A lithographic method comprising following steps: A) filling a mold having a patterned surface with a phase change composition at a temperature above a phase change temperature of the phase change composition, where the phase change composition is a solid below the phase change temperature and the phase change composition is a fluid above the phase change temperature; followed by step B) contacting the phase change composition with a substrate; followed by step C) hardening the phase change composition to form a patterned feature on the substrate by cooling the phase change composition to a temperature below the phase change temperature; followed by step D) separating the mold and the patterned feature; optionally followed by step E) etching the patterned feature; optionally followed by step F) removing the phase change composition; optionally followed by step G) cleaning the mold; and optionally followed by step H) repeating steps A) to G) reusing the mold; to obtain a patterned feature on the substrate, with the proviso that the phase change composition comprises an organofunctional silicone wax.
