METHOD FOR SINTERING OXIDIZING METAL NANOPARTICLES

摘要

A method of the sintering oxidation metal nanoparticle is provided to use the copper nanoparticle ink in the organic substrate like PCB by maintaining the high conductivity even when sintering the metal nanoparticle canning be oxidizable in the low temperature less than 300 ° C. A method of the sintering oxidation metal nanoparticle includes the steps of: the metal layer is formed in the top of the substrate into the ink-jet method by using the oxidation metal nanoparticle ink; in airborne, the metal layer is plasticized at 140~300 ° C with the first; the metal layer is plasticized at 140~300 ° C under the reducing atmosphere mixing one with the inactive gas among the organic acid, the alcohol and their mixture with the second; the ambient gas is removed.
