摘要 |
This invention relates to a stamper for optical disc and a method for manufacturing an optical disc by using this stamper. A photoresist is applied to a substrate (2) and this photoresist is exposed, developed and then transferred to form a disc master which has a recess/protrusion pattern formed on its one side. The one side of the disc master (20) is etched to narrow the width of a protruding part constituting the recess/protrusion pattern, and the recess/protrusion pattern of the disc master (20) with the reduced width of the protruding part is transferred to form a stamper (30). The recess/protrusion pattern provided on the stamper (30) is transferred to form a predetermined pattern on a substrate of an optical disc. <IMAGE> |
