図2は、TFT30の構成の一例を示す断面図である。本実施形態におけるTFT30は、ボトムゲート型である。
図3は、TFT30が適用された有機電子デバイス40の構成の一例を示す断面図である。
図4は、ゲート絶縁層33及びパッシベーション層37の成膜手順の一例を示すフローチャートである。図4に示すフローチャートは、所定のプログラムに従ってコントローラ27が成膜装置10の各部の動作を制御することによって実行される。また、図4に示すフローチャートは、図2に示したTFT30の製造方法の一例を示している。
ここで、ゲート絶縁層33(つまり、酸化シリコン膜33a及び窒化シリコン膜33b)の成膜時における基板Sの温度と成膜後のゲート絶縁層33の膜質との関係について説明する。図5は、酸化シリコン膜33aの成膜時における基板Sの温度と成膜後の酸化シリコン膜33aの膜密度との関係の測定結果を示す図である。図5において、横軸は、基板Sの温度[℃]を示し、縦軸は、酸化シリコン膜33aの膜密度[g/cm3]を示す。
図9は、PBTS(Positive Bias Temperature Stress)法による、TFTの閾値電圧の変動量の測定結果を示す図である。図9において、「比較例」は、SiH4ガスと、O2ガスとの混合ガスにより成膜されたSiO膜であるパッシベーション層を有するTFTに対応する測定結果である。なお、閾値電圧とは、ドレイン電流が流れ始める時のゲート電圧を指す。
図10は、μ‐PCD(Microwave PhotoConductivity Decay)法を利用した保護膜のバリア性の検証結果を説明するための図である。μ‐PCD法は、酸化物半導体に対してレーザ光及びマイクロ波を照射し、酸化物半導体中のキャリアの密度と相関性を有するマイクロ波の反射波の強度(以下、「反射波強度」と呼ぶ)を測定する手法である。μ‐PCD法を利用した検証実験では、本実施形態の保護膜(パッシベーション層37)によって覆われた酸化物半導体に対して、H2ガスのプラズマによるプラズマ処理を施し、プラズマ処理前の酸化物半導体の反射波強度と、プラズマ処理後の酸化物半導体の反射波強度とを比較した。図10において、「INITIAL」は、H2ガスのプラズマによるプラズマ処理前の酸化物半導体の反射波強度を示し、「After H plasma」は、H2ガスのプラズマによるプラズマ処理後の酸化物半導体の反射波強度を示している。
図11は、ゲート絶縁層33、パッシベーション層37及び封止膜46の成膜手順の一例を示すフローチャートである。図11に示すフローチャートは、所定のプログラムに従ってコントローラ27が成膜装置10の各部の動作を制御することによって実行される。また、図11に示すフローチャートは、図3に示した有機電子デバイス40の製造方法の一例を示している。なお、図11において、ステップS111〜S118は、図4に示したステップS101〜S108にそれぞれ対応するので、その説明を省略する。
なお、本発明は、上記した実施形態に限定されるものではなく、その要旨の範囲内で種々の変形が可能である。
