Abstract: Provided is a method of fabricating a nanoimprint mold which can form sub-100 nm fine pattern structures. The method includes forming patterns on a first substrate using an E-beam lithography (EBL) process, and transferring the patterns formed on the first substrate to a second substrate using a nanoimprint lithography (NIL) process to complete an NIL mold. Accordingly, the method can easily fabricate the nanoimprint mold at low costs on a quartz or glass substrate, which is not suitable for an EBL process to produce sub-100 nm patterns, by utilizing the advantages of the EBL process with a resolution of tens of nanometers.
