| titleOfInvention | Preparation method of nano silver paste |
| abstract | A method for preparing a nano silver slurry, which uses an organic acid (heptanoic acid or propionic acid) as a protective agent, and uses silver nitrate as a source of silver ions to reduce silver nanoparticles having a surface protected by an organic acid. The particle size is 45 nm; in addition, silver precursors belonging to organometallics are synthesized, and the pores remaining in the nanosilver sintering process are filled by the characteristics of cracking and reduction at 200 °C. After the nano silver particles (addition of heptanoic acid or propionic acid), the silver precursor and the solvent are mixed, the nano-silver paste of the present invention is formed, and the prepared nano silver slurry is heated and sintered. A lower resistivity can be measured; if copper-to-copper bonding is performed with continuous hot pressing, shear testing of the sample results in high bonding strength. Thereby, it is sufficient to prove that the present invention can significantly improve the bonding strength of the nano silver paste by adding a silver precursor to form a high-strength nano silver paste. |
