冷却管及び撹拌機を持つ3つ口フラスコ(500ml)を窒素置換した後、通常の減圧蒸留法で蒸留した2−シアノエチルアクリレートモノマーを70g加えた。次いで、重合溶媒として脱水処理を行ったアセトンを163g、モノマーに対するモル数比が0.01となるようラジカル開始剤として2,2’−アゾビスイソブチロニトリルを加え、更に連鎖移動剤として0.001モルのラウリルメルカプタンを加えた。窒素導入管を接続し、反応温度60℃で反応時間300分の条件で反応を行った。終了後、室温まで冷却し、過剰量のメタノールへ反応液を析出させ、更に析出物をアセトンに溶解し過剰量のメタノールで析出することを数回繰り返した。その後、精製された析出物を乾燥し、ジメチルホルムアミドを溶媒とする20℃における20質量%の粘度が305mPa・s、40℃/1kHzの比誘電率が約11、軟化温度が約30℃のポリ(2−シアノエチルアクリレート)約63gを得た。
次に、上記酸化アルミニウム薄膜を表面に有するゲート電極Al上に、上記絶縁体層形成溶液を、5,000rpmで60秒間スピンコートし、180℃で24時間加熱し、溶剤を蒸発させると共に硬化させ、0.3μmの絶縁体層を形成した。
次に、銅フタロシアニンを用い、真空蒸着法により膜厚が50nmの半導体層を作製した。
基板を−20℃に冷却し、半導体層にメタルマスクを介して、背圧5×10-4Pa以下の条件でRFスパッタ法により、Auを40nm蒸着した。ソース・ドレイン間の距離と電極幅は、それぞれ50μmの間隔(図1においてL=50μm)、4.0mm幅(図1においてW=4.0mm)であった。
作製した有機電界効果トランジスターに負のゲート電圧を印加して、電流−電圧(ISD−VSD)特性を室温(25℃)で測定したところ、図2のように、ゲート電圧の増加と共に電流値が増加していく、典型的なp型のトランジスター特性を示した。
次に、ソース・ドレイン電流−ソース・ドレイン電圧曲線のチャネルコンダクタンスから移動度(μ)を見積もった。移動度は2.0×10-3cm2/Vsであり、
閾値電圧VTは−2.7Vであり、通常アモルファスシリコン並の5V以下の低電圧で駆動する。
