| Outline of Final Research Achievements |
A noble fine nanoscale patterning technique of metallic electrodes and organic semiconductors from solution process was developed for fabrication of low-cost and high-performance transistors. The key technique developed for is the patterning of fluorinated polymer films of which the hydrophobicity was used as the repellent bank. The newly developed photoresist was able to form spin-coated films even on the hydrophobic fluorinated polymers and enabled patterning of hydrophobicity on the substrate, which enabled patterning of metal or semiconductor films by using selective dewetting technique. Furthermore, this technique was utilized for fabricating backplane circuits of active-matrix display having 100 ppi resolution.
