Method for manufacturing cubic copper or copper oxide nanoparticles










Image Number 4 for United States Patent #7858025.

The present invention relates to a method of manufacturing cubic copper nanoparticles, and in particular, to a method including (a) mixing and agitating a copper precursor and an amine compound; (b) raising the temperature of the mixed solution up to 90-170.degree. C. and reacting it at the same temperature; (c) adding the mixture to nonaqueous solvent to lower the temperature of the solution to 20-50.degree. C. when the incubation completes; and (d) precipitating and obtaining the nanoparticles by adding an alcohol solvent to the mixture. According to the invention, while conductive wiring is formed metal nanoparticles can be manufactured not in sphere but in cubic shape so that void between particles can be efficiently removed and the height of wiring can be raised.
