Abstract
An exemplary method for making a soft mold is provided. A transparent substrate is provided. A to-be-solidified film is formed on the transparent substrate. A stamper and a guiding plate are further provided. The guiding plate is positioned between the stamper and the to-be-solidified film. The stamper inserts one of the through holes of the guiding plate. The first alignment mark is aligned with one of the second alignment marks. The stamper is pressed into the to-be-solidified film. The pressed portion of the to-be-solidified film is solidified to obtain a second molding surface on the to-be-solidified film. The previous steps are repeated for the stamper and the rest of the through holes of the guiding plate to obtain a soft mold having a plurality of the second molding surfaces.
