Outline of Final Research Achievements

This research is to develop, ahead of the rest of the world, next-generation electronics packaging technology that will make it possible to use electronic packages in high-temperature environments and to connect them to flexible substrates. This has been achieved by developing an electrically conductive nanowire surface fastener (ECNSF) that, through self-organization, organically combines the multiple-channel electron transport function of patterned three-dimensional metallic nanowire arrays with the bonding function between nanowires. Furthermore, this research has also been succeeded with creating, for the first time in the world, innovative cold-temperature packaging technology that is not an extension of conventional technologies by clarifying the multiple-channel electron transport mechanism of metallic nanowires, the van der Waals force that acts between nanowires, and the mechanical phenomena of the hook and loop structures of nanowires.
