Outline of Research at the Start

本研究では、「フローティング(浮遊)ゲート型有機不揮発性メモリトランジスタ技術」と、「柔軟性に優れたフレキシブルトランジスタ技術」を融合させることで、フレキシブル有機トランジスタ素子間の特性バラツキを動的に抑制する「特性補償技術を開発」する。これにより、特性バラツキを動的に5%以内に抑え込む技術基盤を確立する。

Outline of Final Research Achievements

This research is an effort to develop a "characteristic compensation technology" that dynamically suppresses characteristic variations among flexible organic transistor elements by integrating "floating gate type organic nonvolatile memory transistor technology" and "flexible transistor technology" to realize flexible transistor integrated circuits with stable operation. This is an effort to realize flexible transistor integrated circuits that operate stably. Specifically, we have optimized the process of floating gate type flexible organic transistors, realized suppression of threshold variation, and developed a further property compensation technology, "property compensation technology by optical process". These results were published in the world-renowned journals Advanced Materials and Nature Communications, and received high acclaim.

Academic Significance and Societal Importance of the Research Achievements

有機薄膜トランジスタは、低温、低エネルギー、低環境負荷で製造できる次世代エレクトロニクス用スイッチ素子として期待されている。一方で、有機材料の本質的な分子結合に頼り、構造を形成している界面が多く、トランジスタとしての特性不均一性が大きな課題となっている。これは有機材料の多様性と表裏一体の関係にあり、本質的な課題であった。そこで本研究は、有機薄膜トランジスタ作成後に、特性の不均一を抑制するための特性補償技術を提案し、取り組んできた。その結果、生体計測センサなどの実用性に耐えうる特性均一性を確保できることを示した。さらに従来知られていた技術とは異なる新たな特性補償技術を実現することに成功した。
