Description
これら不純物が半導体層に含まれる場合、不純物ドーピングによる共役系高分子の絶縁性の低下からくるサブスレッショルド特性の低下のみならず、不純物イオンの分極によるトランジスタ特性のヒステリシス発現などトランジスタ特性を著しく低下させてしまう。また、他の解決手法として、共役系高分子材料の残留触媒(金属イオン)の除去、溶媒の蒸留・用具の洗浄の徹底、グローブボックスなど脱酸素・脱水分雰囲気制御下での作製等の対策も講じられている。しかしこれらには専用の設備が必要であること、また、これらの操作は徹底して行わなければ効果が期待できないという制約が存在する。その他、共役系高分子材料を用いる有機電界効果型トランジスタに関して、色々な提案がなされているが、前記問題点を解決するに至ってはいない(例えば、特許文献1〜6参照)。
本発明の有機電界効果型トランジスタは、前記有機半導体層、ソース電極、ドレイン電極、ゲート絶縁層、ゲート電極の他、通常、電子デバイスに用いられる配線や保護膜等から構成される。
