제목 Low-cost Fabrication of a Transparent Hard Replica Mold using SiO2-TiO2 sol-gel for Imprinting Lithography
초록 We introduce a new and cost-effective fabrication method for transparent and hard replica mold for imprinting lithography such as NIL and S-FIL. The method is founded on the use of replica hard mold from master using polymer copy as a carrier. In order to preserve intrinsically damage due to the direct contact between a master and a polymer on substrate and the contamination of master in imprinting process, a hard mold was replicated from master using the polymer copy as a carrier. We suggest a SiO2-TiO2 sol-gel process for mold fabrication under low temperature (45°C) and low-pressure (~0.3MPa), and flexible polymer copy as carrier for replicating a transparent hard mold from original master pattern. As this replica mold is transparent and has a highly hardness as well as a glass, it has a potential for imprinting lithography such as NIL and S-FIL.
