| Outline of Final Research Achievements |
1) Organic-inorganic hybrid bonding without high temperature and vacuum was realized for electronics packaging materials and automotive structural materials. 2) In novel bonding method, the vacuum ultraviolet irradiation in humidified nitrogen enabled the surface cleaning, partial deoxidization of native oxide, and ultrathin bridge formation, via single process (V-VUV method). Different bridge structures were available by using such as water and anmonium solution, and the thickness was tunable to obtain sufficient interdiffusion for cohesive fracture. 3) As a basic prototype of "lightweight and SMART strucural material," a hybrid body, which was composed of rolled Ti foil and PEEK and a resistance-change strain sensor substrate amid, was structured by means of V-VUV method. 4) Although it was beyond the original plan, a feasibility of water-proof bridge structure at the organic-inorganic interaface was shown.
