Abstract
A method for forming a die, including forming a pre-formed mold by providing a preliminary layer on a substrate and performing a micro-machining process on the preliminary layer. Due to the micro-machining process, the method can fabricate a pre-formed mold with high precision for forming a mold. The die is fabricated by the mold for performing a molding process to obtain a workpiece with a predetermined shape.
