A method is provided to make a nano-silver paste. An organic acid is used as a protective agent. Silver nitrate is used as a source of silver ions to reduce silver nanoparticles on a surface protected by the organic acid. The particle size of the silver nanoparticle is 45 nanometers. In the other hand, a silver precursor of organic metal is synthesized. The organic metal is cracked at 200 celsius degrees (° C.) to fill pores left during sintering. After mixing the silver nanoparticle, the silver precursor and the solvent, the nano-silver paste is obtained. After being heated at 250° C. for 30 minutes, the nano-silver paste has a resistance of (3.09±0.61)×10.sup.−5 Ω.Math.cm. By being heated at 250° C. and applied with a pressure of 10 MPa to be hot-pressed for 30 minutes for joining copper to copper, the nano-silver paste obtains a bonding strength reaching 36 MPa.
