PATTERN FORMING METHOD, PATTERN FORMING DEVICE, METHOD FOR MANUFACTURING RECORDING MEDIUM, AND METHOD FOR MANUFACTURING MEMBER

摘要

The method involves generating a photo-sensitive unit on a surface of a substrate i.e. glass substrate, and gathering ultra-short pulse laser. The pulse laser is radiated on the substrate by positioning a point of focus of the laser with a boundary surface between the substrate and the photo-sensitive unit. The pulse laser is radiated to a limiting surface by transmitting the pulse laser through the substrate. The photo-sensitive unit reacting with the pulse laser or the photo-sensitive unit not reacting with the pulse laser are selectively removed. Independent claims are also included for the following: (1) a process for manufacturing a recording medium (2) a method for manufacturing a patterned unit.
