A method for making a mold, the method includes steps of: providing a substrate and a retaining member, the retaining member being made of polytetrafluoroethylene, and being ring-shaped; engaging the substrate with the retaining member; disposing viscous liquid polydimethyl siloxane containing material on the substrate within the retaining member; rotating the retaining member and the substrate to cause the polydimethyl siloxane containing material to spread out on the substrate and form a polydimethyl siloxane containing layer; press-molding the polydimethyl siloxane containing layer using a stamper to form one or more molding portions on the polydimethyl siloxane containing layer; solidifying the polydimethyl siloxane containing layer with the one or more molding portions; separating the stamper from the polydimethyl siloxane containing layer; and separating the substrate from the retaining member to obtain a mold.
