title = "Development of micro conductive ball for Anisotropic Conductive Film (ACF) using ultrafine Ni nanoparticle synthesized by low temperature method",
abstract = "In this work, micro-sized conductive ball for 20 μm pitch fine pitch interconnection was successfully fabricated using ultrafine Ni nanoparticle of which size less than 5 nm. The ultrafine Ni nanoparticle was successfully synthesized using low temperature synthetic method, and was uniformly coated onto polymethylmethacrylate(PMMA) miro core ball. Thickness of the Ni coated layer was well controlled as intended. Also, Au was successfully plated onto the Ni coated layer by elec-trolessplating. Surface roughness of the Au/Ni coated ball is smooth due to the ultrafine and uniformly distributed Ni nanoparticle. The Au/Ni layer shows good adhesive and electrical properties of which resistance is 6 Ω/ball compatible to the fine pitch interconnection. So, micro-sized conductive ball was successfully fabricated compatible to 20 μm pitch interconnection.",
