| Outline of Final Research Achievements |
1. Realization of 1-Micro-Resolution Printing of Electronic Circuits and Devices. In this research, we developed the spontaneous patterning based on the parallel vacuum ultraviolet (PVUV) technique, which enabled the homogeneous integration of complex, high-resolution electronic circuits even on large-scale, flexible, transparent substrates.
2. Large-area, solution-processed discrete organic thin-film transistors. In this research, we developed a homogeneous dewetting on large-area micro-droplet arrays, which was caused by the gravity-induced deformation of droplets on a tilted substrate. This method allowed the deposition of discrete organic semiconducting thin films for fully-printed organic thin-film transistors (OTFTs).
