A method for manufacturing a substrate for use in a stamper manufacturing process and a substrate which is used in stamper manufacturing process to be used in producing optical discs, includes exposing, developing and heating of a photosensitive film that has been coated onto a substrate
A method of manufacturing a stamper for producing optical discs involves the application of a photoresist film to a substrate and subsequently structuring the photoresist film by exposing and developing the photoresist film. The method is characterized in that an electrically conduct
