Patent ID: 8323553

Claim:
A method for manufacturing a substrate with surface structure by employing photothermal effect, comprising the steps of: providing a first substrate; distributing a plurality of nanoparticles on the provided first substrate, a particle size of each of the plurality of the nanoparticles being between 2.5 nm and 500 nm, a material of the nanoparticles being selected from a group consisting of Au, Cu, Ag and a combination thereof, said distributing including: fixing the plurality of the nanoparticles on one side of a transparent substrate, the transparent substrate being transparent to light of a specific wavelength; and after fixing the plurality of the nanoparticles on said one side of the transparent substrate, placing the transparent substrate on the provided first substrate, wherein said one side of the transparent substrate is adjacent to the provided first substrate; irradiating the plurality of the nanoparticles on the provided first substrate with the specific wavelength, so that the irradiated nanoparticles convert irradiating energy to thermal energy, at least a part of the irradiated nanoparticles existing and maintaining in a form of a nanoparticle after being irradiated; forming a plurality of pores in a surface of the provided first substrate through the thermal energy, such that locations and shapes of the pores are at locations and have shapes of their respective irradiated nanoparticles; and after forming the pores, removing the irradiated nanoparticles in the form of the nanoparticle from the provided first substrate to obtain the first substrate with the pores formed, including: removing the irradiated nanoparticles together with the transparent substrate from the provided first substrate to thus remove the irradiated nanoparticles from the provided first substrate to thus remove the irradiated nanoparticles from the pores.
