Title:
METHOD FOR MANUFACTURING STAMPER FOR OPTICAL DISK
Document Type and Number:
Japanese Patent JP2001283471
Kind Code:
A
Abstract:
To provide a method for manufacturing a stamper for an optical disk, in which the number of the manufacturing steps can be reduced and the layer constituted of a resist material can be removed suitably.
This method for manufacturing the stamper 10 for the optical disk comprises a die forming step to form a die 9, a resist layer removing step to remove a resist layer formed on the die 9 and a succeeding processing step. The resist layer is removed by treating with ozone-containing water. The resist layer is preferably removed so that the contact angle of the surface of the die 9 with water becomes 50° or smaller after 3 hours have passed since the resist layer was removed.
