METAL NANOPARTICLE DISPERSION, METHOD OF PRODUCING METAL NANOPARTICLE DISPERSION AND BONDING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a metal nanoparticle dispersion that enables bonding at a low temperature (for example, 200°C or less) and can improve mechanical characteristics and electrical characteristics at the bonded portion.SOLUTION: A metal nanoparticle dispersion has a metal nanoparticle having a surface at least a part of which is coated with a 8C or more amine A and a dispersion medium for dispersing the metal nanoparticle. The dispersion medium includes an amine B being a 7C or less primary, secondary or tertiary amine and being a linear alkylamine or alkanolamine.
