Laser sintering process is a promising technique which can sinter an electrode pattern selectively without mask. In this study, metal oxide nanoparticle with several solvents and various molar ratio of polyvinylpyrrolidone (PVP) is prepared to optimize a fabrication of a copper electrode pattern. As a result, the solvent with exothermic heat flow and low absorption cross-section shows better pattern shape and higher conductivity in selective laser sintering. Additionally, PVP, a reductant, affects to the quality of electrode, too. High molar ratio and large amount of PVP make the laser sintering process window broad and the specific resistivity low.
