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.

A stamper comprising:
- a base having a surface, and a first alignment mark formed on the surface;
- and
- a molding portion protruding from the surface, the molding portion comprising a first molding surface at an opposite side thereof to the base.
A method for making a soft mold, the method comprising:
- (1) forming a to-be-solidified film on a transparent substrate;
- (2) providing a guiding plate, the guiding plate comprising a plurality of through holes defined therein, and a plurality of second alignment marks adjacent to the respective through holes;
- (3) positioning the guiding plate between a stamper and the to-be-solidified film, the stamper comprising a base having a surface, and a first alignment mark formed on the surface;
- (4) inserting the stamper through one of the through holes of the guiding plate;
- (5) aligning the first alignment mark with one of the second alignment marks;
- (6) pressing the stamper into the to-be-solidified film;
- (7) solidifying a pressed portion of the to-be-solidified film to obtain a second molding surface on the to-be-solidified film;
- (8) repeating the steps (4) through (7) to obtain a soft mold having a plurality of the second molding surfaces.
