Ink-jet printable Ag nanoparticles (NPs) and Ag-Cu alloy NPs were synthesized by the polyol method, and interconnection lines composed of these NPs were fabricated on poly(ether sulfone) substrates. The effect of optical heating on the resistivity of the interconnections was investigated as functions of the irradiation time and power of the 488-nm wavelength light. The resistivities of the interconnection lines composed of the NPs were decreased by 7-10 times after the irradiation of the light with a power of 400 mW for 30 min, compared with the interconnection lines composed of the as-synthesized NPs. In addition, the change in the current of the interconnection line when the substrate is bent is discussed in this paper.
