Abstract
A cellulose-based gas permeable mold having thermal crosslinking group for nanoimprint lithography has been developed to prevent transcriptional defects by volatile solvents from nanoimprinting materials. 3 wt.% of thermal initiator was required for producing the cellulose-based gas permeable mold. The void on 10 μm line structure of imprinted UV crosslinked resin with acetone as volatile solvents in nanoimprint lithography process using non-gas permeable mold was significantly removed using the cellulose-based gas permeable mold due to its high oxygen gas permeability. The cellulosebased gas permeable mold allows the employment of solvent including imprinting materials such as compounds and alloy particle.
