  • Composite metallic ultrafine particles and process for producing the same
    Patent number: 6871773
    Abstract: The present invention relates to composite metallic ultrafine particles which have excellent dispersion stability and can be produced on an industrial scale, and a process for producing the same, and a method and an apparatus for forming an interconnection with use of the same. A surface of a core metal produced from a metallic salt, a metallic oxide, or a metallic hydroxide and having a particle diameter of 1 to 100 nm is covered with an organic compound including a functional group having chemisorption capability onto the surface of the core metal.
    Type: Grant

  • Bonding material and bonding method
    Publication number: 20040245648
    Abstract: There is provided a bonding material and a bonding method which enable lead-free bonding that can replace high-temperature soldering. The bonding material of the present invention comprises a dispersion in an organic solvent of composite metallic nano-particles having such a structure that a metal core of a metal particle having an average particle diameter of not more than 100 nm. The bonding material can be advantageously used in a stepwise bonding process containing at least two bonding steps.
