MASTERING BASED ON HEAT-INDUCED SHRINKAGE OF ORGANIC DYES

摘要

The present invention relates to a method for providing a high-density relief structure in a recording stack of a master substrate, particularly a master substrate for making a stamper for the mass-iabrication of optical discs or a master substrate for making a stamp for micro contact printing. Furthermore, the present invention relates to a master substrate for creating a high-density relief structure, particularly a master substrate for making a stamper for the mass-fabrication of optical discs or a master substrate for making a stamp for micro contact printing. The invention also relates to a special use of a master substrate that comprises a dye layer, as well as to a master substrate comprising a high-density relief structure. Furthermore, the present invention relates to a stamper for the mass-fabrication of optical discs, an optical disc, and a microprint. In accordance with all aspects of the present invention a high-density relief structure required for all of the above applications is directly or indirectly formed by laser pulse induced shrinkage of dye layer material.
