METAL NANOPARTICLE DISPERSION, PROCESS FOR PRODUCING METAL NANOPARTICLE DISPERSION, AND BONDING METHOD

摘要

Provided is a metal nanoparticle dispersion which renders low-temperature (e.g., 200°C or lower) bonding possible and which can make the bonded part have satisfactory mechanical properties and electrical properties. The metal nanoparticle dispersion comprises metal nanoparticles in which at least some of the surface has been coated with a C8 or higher amine (A) and a dispersion medium for dispersing the metal nanoparticles, wherein the dispersion medium contains an amine (B) which is a primary, secondary, or tertiary, C7 or lower amine and is a linear alkylamine or alkanolamine.
