Fabrication method of stamper for optical information recording medium, master disk of stamper for optical information recording medium, and optical information recording medium |
摘要 |
The following steps are included: a step of changing crystal states of the specific portion of an resist layer of a master disk having an etching layer and the resist layer formed on the etching layer through exposure, a step of removing the specific portion, a step of removing the portion of the etching layer overlapping the removed portion of the resist layer, a step of forming a conductive film from which the resist layer is removed, a step of performing electroforming by using the conductive film as an electrode, and a step of exfoliating the etching layer from the conductive film. |
