| Research Abstract |
The physical process during the local rapid heating of metal nanoparticle by laser irradiation and the laser direct writing of micro-wiring were studied. By laser irradiation to a metal nanoparticle, the laser energy is effectively absorbed by plasmon band of the metal nanoparticle and immediately converted to thermal energy. The inhibition of oxidation during Cu micro-patterning using Cu nanoparticle and the reduction of Cu diffusion into Au coating film prepared by sintering of Au nanoparticle film on Cu substrate were developed by applying the laser irradiation to metal nanoparticles.
