Disclosed is a method of micro/nano imprinting, which applies soft mold, pre-shaping sealing film, and soft holder arrangements to the micro/nano structure imprinting process of the curved substrates. The method of the present invention can prevent the curved surface from crumbling, which may result from high gas pressuring, and can obtain uniform imprinting pressure distribution throughout the whole curved substrate. Moreover, replicating micro/nano structures onto double-sided curve, both convex and concave, surfaces can also be achieved. |
