发明名称 Method for manufacturing optical discs.
摘要 <p>The present invention provides a method for manufacturing an optical disc comprising the steps of: forming a resist film onto a glass substrate; forming a barrier coated layer onto the resist film; forming a contrast enhancement lithography (CEL) material layer onto the barrier coated layer; forming a pit pattern by effecting an exposing treatment with the resist film; peeling off the CEL material layer from the barrier coated layer; developing the resist film being exposed to form a resist master board; plating the resist master plate being developed to form a stamper; effecting an injection molding by utilizing the stamper to form a disc; forming a reflection film onto the disc; and forming an overcoated layer onto the reflection film. &lt;IMAGE&gt;</p>
