を特徴とする離型層付きモールドの製造方法である。
図1(b)は、モールド30に離型層31を設けた様子を示した概略断面図である。図1(b)に示すように、モールド30には、少なくとも所定のパターンが形成された部分に離型剤を塗布することにより離型層31を設ける。
本発明者は、上述のようにモールド30を高品質に再生するためには、当該モールド30の表面に形成された化学的に非常に安定なフッ素化合物からなる離型層31を化学的に変性させることが有効であるという知見を得た。
以上のような本実施形態においては、以下の効果を得ることができる。モールドの再生処理において、化学的に非常に安定なフッ素化合物からなる離型層31を、まず化学的に変性させることにより、離型剤分子を分解させるため、その後の洗浄工程において容易に離型層31を形成する離型剤を除去することができる。
本実施例においては、深さ30nm、ライン15nmかつスペース10nmのハーフピッチ25nm周期構造のラインアンドスペースパターンが設けられている石英基板からなるモールド30を用いた。このモールド30を、VERTRELXF-UP(VERTRELは登録商標 三井・デュポンフロロケミカル株式会社製)で0.5wt%に希釈した下記化合物(上記[化1]と同じ)を含む離型剤に5分間浸漬した。但し、mは自然数である。
本実施例においては、下記化合物(上記[化2]と同じ)を含む離型剤を用いる以外は実施例1と同様に行った。フッ素のF1sスペクトルを観察したところ、実施例1と同様F1sピークはほとんど観察できなかった。但し、mは自然数である。
比較例においては、実施例と同様の手法により作製した離型層付きモールドを3つ用意し、今度は紫外線を照射する時間依存性を検討した。1例目は全く紫外線を照射しない場合、2例目は照射時間を5分間とする場合、3例目は照射時間を10分間とする場合とする。いずれの場合も、実施例と同様に、熱硫酸、冷硫酸で各30分間洗浄処理し、さらに純水、IPAにて洗浄処理を行った。
実施例、比較例からも分かるように、離型層を化学的に変性させるための処理である紫外線の照射には時間依存性があり、中心波長172nmの紫外線で2分間の照射時間が、離型剤の除去には非常に高い効果を示すことが分かった。
50mW/cm2×120sec=6000mJ/cm2
このことから、紫外線光源の出力の中心波長が150~200nmの範囲で、5000~7000mJ/cm2の範囲の累積照射エネルギーとすることにより、上記の実施例と同等の効果が生じるものとも考えられる。
