Description
したがって、ナノインプリントリソグラフィは、光リソグラフィ技術に代わり、半導体デバイス、オプトデバイス、ディスプレイ、記憶媒体、バイオチップ等の製造への適用が期待されている技術である。このことから、ナノインプリントリソグラフィに用いる光ナノインプリントリソグラフィ用硬化性組成物について様々な報告がなされている(特許文献2、3)。
ここで、上述より、本発明の課題は、高透過率、高屈折率及び低誘電率を有する膜を形成するインプリント材料を提供することである。具体的には、透過率については、例えば、95%以上、好ましくは98%以上の高い透過率を有する膜を形成する材料の提供を目的とし、屈折率については、例えば、1.57以上、好ましくは1.60以上の高い屈折率を有する膜を形成する材料の提供を目的とし、誘電率については、例えば、2.0以上3.2以下、好ましくは3.0以下の低い誘電率を有する膜を形成する材料の提供を目的とする。
とりわけ、本発明の特徴は、透過率、屈折率及び誘電率等の諸特性について全て満足する性能を有する膜を形成するインプリント材料を提供することにある。
また、本明細書では、形成されるパターンサイズがナノメートルオーダーに限らず、例えば、マイクロメートルオーダーである場合を含む光ナノインプリント技術を光インプリントと称する。さらに、本明細書では、“誘電率”とは比誘電率を意味する。
すなわち、本発明は、
(A)成分、(B)成分、及び(C)成分を含有し、前記(A)成分及び前記(B)成分の合計100質量部に基づいて、50乃至95質量部の(A)成分、及び50乃至5質量部の(B)成分をそれぞれ含有するインプリント材料。
(A)成分:下記式(1)で表されるビスアリールフルオレン骨格を有する化合物
(B)成分:分子内に少なくとも1個の重合性基を有する化合物
(C)成分:光重合開始剤
本発明のインプリント材料は、光硬化が可能であり、かつその硬化膜は、モールドの離型時にパターンの一部の剥がれが生じないため、所望のパターンが正確に形成された膜が得られる。したがって、良好な光インプリントのパターン形成が可能である。
また、本発明のインプリント材料は、任意の基材上に成膜することができ、インプリント後に形成されるパターンが転写された膜は、光学部材だけでなく、電界効果トランジスタ等の半導体素子の層間絶縁膜及び/又はゲート絶縁膜に好適に用いることができる。
さらに、本発明のインプリント材料は、分子内に少なくとも2個の重合性基を有する化合物の種類を変更することで、硬化速度、動的粘度、膜厚をコントロールすることができる。したがって、本発明のインプリント材料は、製造するデバイス種と露光プロセス及び焼成プロセスの種類に対応した材料の設計が可能であり、プロセスマージンを拡大できるため、光学部材の製造に好適に用いることができる。
