The project is aimed at developing the mold fabrication and the imprinting recipe for nano-imprint (NIL). For fabrication of a nano-imprinting mold, the electron beam lithography and ICP(Inductively Coupled Plasma) dry etching will be mainly employed to structure the mold of high aspect ratio. As for the nano-imprinting process, the hot-embossing will be employed, and the molds will be tested to form the nanopatterns, and then replicate the pattern to the polymer on the substrate.
