Description
一方、特許文献1には、ラビング基板を純水で超音波洗浄して高いプレチルト角(pretilt angle)を安定に形成させる方法が提案されている。ところが、ディスプレイ製造工程に超音波を導入することは容易ではなく、純水による洗浄方法は最近要求されている洗浄液の物性を満たしていない。特許文献2には、ラビング基板の表面をブラシを用いて洗浄する方法が提案されているが、ブラシから発生する2次汚染物および汚染物の基板に対する再付着などにより洗浄効果を期待することができない。
表1に記載された成分を所定の含量に応じて攪拌器付きの混合槽に仕込み、常温で1時間500rpmの速度で攪拌して洗浄液組成物を製造した。

1.PI配向膜の損傷およびパーティクル洗浄力の評価
PI配向膜をラビングした基板(5×5×0.7cm)を大気中に24時間放置して大気中の各種有機物、無機物、パーティクルなどに汚染させた後、スプレー式ガラス基板洗浄装置を用いて2分間常温で実施例1〜11および比較例1〜8の洗浄液組成物で洗浄した。洗浄の後、超純水で30秒洗浄した後、窒素で乾燥させた。前記基板を走査電子顕微鏡(SEM:日立社、モデル名S−4700)で検査してPI配向膜の損傷有無評価と共に、基板の表面に残っている異物の粒子数で洗浄力を評価した。
ガラス基板を大気中に24時間放置して大気中の各種有機物、無機物、パーティクルなどに汚染させた後、0.5μLの超純水滴を滴下して洗浄前の接触角を測定し、表面汚染を確認した。洗浄は、容量250mLのビーカーに、実施例1〜11および比較例1〜8で製造された洗浄液組成物100mLを入れ、常温(25℃)で2分間担持させた後、超純水で30秒洗浄し、しかる後に、窒素で乾燥させた。前記ガラス基板上に0.5μLの超純水滴を滴下して洗浄後の接触角を測定した。
配線損傷評価のために、Mo/Al/Mo配線基板でアルミニウム損傷評価を行い、Cu/Ti配線基板を用いて銅損傷評価を行った。評価は、容量250mLのビーカーに、前記実施例1〜11および比較例1〜8で製造された洗浄液組成物100mLを入れ、常温(25℃)で30分間担持させた後、超純水で30秒洗浄し、しかる後に、窒素で乾燥させた。前記基板を走査電子顕微鏡(SEM:日立社、モデル名S−4700)で検査してアルミニウムと銅の損傷有無評価結果を表2に示した。
