本発明は、例示目的のみのために与えられ、添付の特許請求の範囲によって定義される本発明の範囲を限定することを意図しない以下の実施例に照らしてよりよく理解されるであろう。
マスターはシリコンウェハの集束イオンビームリソグラフィによって製造された。二種類のパターンが使用された:
-20μm×20μmの領域上で、1μm離隔された平行線を刻み、次にそれに垂直な線を刻むことによって得られたピラミッドアレイ。刻む深さは測定できなかった(破壊的方法)。
-マスター中にリングを刻むことによって得られた、直径4μmで深さ700nmの刻まれた領域によって囲まれた直径1.8μmの区画(plots)。
モールド上に存在するパターンの一つに近いフィルム厚さにおける変化を原子間力顕微鏡で測定することによって、まず予備実験が行われた。この目的のために、水相対圧力(即ち、相対湿度、RH)の細かい制御が実行された。モールドがフィルムの表面に適用されると、フィルムとPDMS表面との間の毛管力が局所的な変形を誘導し、パターンの周りの材料の変位の原因となる。この実験は、RH<40%ではフィルムが流動性を有しないことを示した。図1に示されたように、プロセスがRH=50%で、次にRH=70%で行われた際に、フィルムの流動性は徐々に高くなった。従ってゾルゲルフィルムは、ソフトNILプロセスの複製ステップ中の相対湿度を調節することによって制御され得るある程度の流動性を示す。
構造の複製に対する相対湿度の影響が研究された。マスター上に刻まれたパターンは、モールド上に、次にゾルゲル試料上に複製され、マスターとレプリカとの間のパターン複製の精度を評価するために、暗視野光学顕微鏡及び原子間力顕微鏡法によって試料が特徴づけられた。精確な複製に加えて、図2に示されたように、マスターのアスペクト比にできるだけ近いアスペクト比が望まれ、ここでZはアスペクト比を示し、それはピラーの直径(それぞれL又はl)に対するピラーの高さ(H又はh)に対応する。h/lがH/Lにできるだけ近いことが好ましい。
実施例1と同様に、ZnO/TiO2フィルムにソフトNIL法が行われた。その加工性とその化学的及び機械的特性を改善し、熱収縮を減らすために、ZnOはTiO2と混合された。
-50:50のZnO:TiO2フィルムを提供するために、1.5gのTiCl4、1.75gのZn(OAc)2,2H2O、20.5gのエタノール、1.62gのH2O、及び0.1gのPluronic(登録商標)F127(PPG-PEGコポリマー)、
-25:75のZnO:TiO2フィルムを提供するために、0.76gのTiCl4、2.63gのZn(OAc)2,2H2O、20.5gのエタノール、1.62gのH2O、及び0.1gのPluronic(登録商標)F127(PPG-PEGコポリマー)、並びに
-5.1gのAl(OiPr)3、33.4gのエタノール、3.42gのHCl(37%)、0.04gのCTAB(セチルトリメチルアンモニウム臭化物、cetyl trimethylammonium bromide)。
1:20:5:0.0002のモル比のTEOS(Aldrich):EtOH(無水):H2O(milliQ):Pluronic F127からなるゾルゲル溶液が準備され、スライドガラス上に堆積された。
