Abstract

A ball-shaped NiP micro particle having good conductive resistance and mono dispersibility and fabricating method thereof and a conductive particle for anisotropic conductive film are described. The ball-shaped NiP micro particle of this invention uses Ni as a main constituent and also comprises P constituent. The structure of the ball-shaped NiP micro particle comprises a core portion having the crystalline structure and a surface portion having the structure where a NiP intermetallic compound disperses in the amorphous substance; the content of P in the surface portion is more than that in the core portion. The conductive particle for anisotropic conductive film of this invention is the ball-shaped NiP micro particle that is covered by AU. The ball-shaped NiP micro particle is fabricated by mixing nickel salt solution, mixed solution of pH regulator agent and pH buffer agent, and phosphorous reductant solution to prosecute a reducing precipitation reaction. When the reducing precipitation reaction starts after mixing the solutions, the pH value is adjusted over 7 and becomes alkaline, and a heating treatment is applied to the ball-shaped NiP micro particle formed by the reducing precipitation reaction.
