Outline of Final Research Achievements |
We aimed to enable the direct fabrication of metal nanoparticle interconnects on any substrate by advancing the drying and sintering process of the ink before the droplets reach the substrate with irradiating xenon light to the ink droplets in flight. Firstly, we succeeded in improving the conductivity of inkjet printed interconnects. Secondly, a new method has been proposed that can be evaluated objectively as a calculated value for the improvement of the ink jet ejection stability, which is a problem particularly in direct fabrication. Thirdly, we developed an inkjet system that can emit xenon light, thereby realizing printing and light sintering in the same system.

Academic Significance and Societal Importance of the Research Achievements |
本研究課題の成果は、インクジェットを用いたプリンテッドエレクトロニクスにおいて、濡れ広がり抑制工程および焼結工程を不要とし、あらゆる基材に対して金属ナノ粒子配線の直接形成が行えるようにするための重要なステップとなった。これまで、濡れ広がり抑制工程と焼結工程が追加で必要となり工程数が多く、インクジェットの強みである低コスト性、高効率性、高生産性を損ねる原因となってしまっていたが、直接形成の実現は、これらのマイナス要因をほぼ全て打ち消す。本研究課題のさらなる推進は、エレクトロニクス製造の裾野を広げ、「電子回路は家庭で印刷して作る」ことが当たり前になるほどに発展・普及する可能性を秘めている。
