Description
t−ブチルアクリレート10g、アクリル酸4g、N−イソプロピルアクリルアミド6gおよびAIBN 0.4gをPGMEA溶媒200gに入れ、60℃で8時間重合反応させた。この重合反応が終了すると、エーテルを入れて沈澱した後、フィルタリングして真空乾燥し、下記の化3に示される、白色固体状のt−ブチルアクリレート−アクリル酸−N−イソプロピルアクリルアミド共重合体を17g得た。図1にこの重合体に対するNMRグラフを示す。
前記実施例1で製造した重合体2.5gと、アミノ酸の一種であるL−プロリン0.04gとを、100gのノルマルブタノールに溶かしてイマージョンリソグラフィ用上部反射防止膜の組成物を製造した。
前記実施例2で製造した上部反射防止膜の組成物を、ウエハー上に2000rpmでコーティングした。このとき、厚さは43nmで、193nmの波長の光に対する透過度は89%で、屈折率は1.58であった。
前記実施例2で製造した上部反射防止膜の組成物を、JSRのAR1221J感光膜(220nm)上に2000rpmでコーティングした。このとき、厚さは、264nmであった。すなわち、本発明による上部反射防止膜の組成物が感光膜を溶解していないことが分かる。
前記実施例4で製造したフォトレジスト膜および上部反射防止膜が形成されたウエハーを蒸溜水に約5分間浸漬し、ウエハーを乾燥した後、その厚さを測定した。このとき、厚さは264.7nmであって、水に浸漬する前に比べて約0.7nmの厚さが増加したことが分かる。すなわち、本発明による上部反射防止膜の組成物が水によって溶解されるか、またはほとんど膨潤されていないことが分かる。
前記実施例4で製造したフォトレジスト膜および上部反射防止膜が形成されたウエハーを2.38wt%のTMAH現像液に約1分間現像し、蒸溜水で洗浄した後、その厚さを測定した。このとき、厚さは、220nmであって、上部反射防止膜の組成物が現像液によって完全に溶解されたことが分かる。
