摘要： A method for manufacturing a glass stamper includes the following steps. First, a diamond film is formed on a substrate. A resist is applied onto the diamond film and a pattern is formed by performing electron beam lithography and development. The diamond film is etched with any one of oxygen and Ar gas using the pattern on the resist as a mask, thereby transferring the pattern to the diamond film. The resist and the substrate are removed to fabricate a diamond mold. Then, a glass stamper is manufactured by glass molding using the diamond mold.
