<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a substrate in which a micro-nano structure can be directly fabricated easily at low cost on a large region of a surface of the substrate by employing photothermal effect. <P>SOLUTION: Nanoparticles are distributed on the surface of the substrate and when a laser beam of a predetermined wavelength is applied to the surface, the nanoparticles on the surface of the substrate are excited by light energy of the laser beam, and the light energy is converted to thermal energy. As a result, the surface structure on the substrate is formed through the thermal energy generated by the excited nanoparticles. Thus, the substrate having a layer of a predetermined pattern is formed. <P>COPYRIGHT: (C)2009,JPO&INPIT |
