| Outline of Final Research Achievements |
New Ag sinter joining technology was developed and the basic mechanism, which enables one to fabricate an excellent joint between two substances with Ag micron particles paste or with sputtering Ag films at low temperature and low pressure in air, was clarified by high resolution TEM with the aid both of the first principle simulation and of the phase diagram simulation. Oxygen was absorbed in the grain boundary of Ag, which becomes liquid, leading Ag-O liquid eruption under compression stress, which reaction was named as "Nano-Volcanic Eruption". The heat-resistance beyond 250 degree C was achieved by Ag sinter joining. The environmental reaction was applied to Cu sinter joining and the possibility of low temperature sinter joining with affordable Cu paste was discovered.
