4−ビニロキシエトキシフェニルジ(4−t−ブチルフェニル)スルホニウム 2,4,6−トリイソプロピルベンゼンスルホン酸塩の合成:
感光性ポリマーの製造:
ポリヒドロキシスチレン20.0g(重量平均分子量[Mw]16400で、[Mw]/数平均分子量[Mn]=1.09)を窒素雰囲気下で1,3−ジオキソラン147mlに溶解後、1,3−ジオキソランを常圧で留去して、系内水分が100ppmまで低減されたのを確認した。得られた反応液を20℃まで冷却し、その反応液に35重量%塩酸25.0μLを添加した。更に、そのものに、実施例1で得られた本発明のスルホン酸塩(4−ビニロキシエトキシフェニルジフェニルスルホニウムパーフルオロブタンスルホン酸塩)を56.2重量%となるように1,3−ジオキソランに溶解した溶液5.70gを、30分間かけて滴下し、30℃で4時間攪拌した。得られた溶液を、4−ジメチルアミノピリジンで中和し、室温の純水667gに滴下し、固体を析出させた。固体をろ別後、1,3−ジオキソランに溶解し、再沈澱処理を施し、35℃で24時間乾燥することによりポリマー22.8gを得た。このポリマーは、1H−NMRによる測定結果から、用いたポリヒドロキシスチレンにおける全水酸基のうち15.8%の所に本発明の上記スルホン酸塩から由来した構造が導入されている構造をとっている感光性ポリマーであることが確認された。
上記の応用例1で得た感光性ポリマー100重量部とトリエタノールアミン0.24重量部とをプロピレングリコールモノメチルアセテート525重量部に溶解し、フィルター(PTFEフィルター)でろ過して液状のポジ型フォトレジストを調製した。このレジストを、スピナーを用いて、シリコンウエハ(直径:4インチ)に塗布し、110℃で90秒間プレベークし、膜厚500nmのレジスト膜を得た。この膜に、キセノンランプ(波長:248nm)により露光し、次いで110℃で90秒間ポストベークを行った。その後、23℃で現像液(2.38重量%のテトラメチルアンモニウムハイドロキサイドの水溶液)を用いて、ブレークスルータイム(一定のエネルギーを照射した後、現像により残膜が皆無になる秒数)を測定した。
上記応用例1にて、実施例1で得られたスルホニウム塩の代わりに実施例2〜7で得られた各スルホニウム塩を用いて、各感光性ポリマーを製造した(感光性ポリマー2〜7)。その各感光性ポリマーを用いて、応用例1の場合と同様に、液状のポジ型フォトレジストを調製し、レジスト膜を得て、露光、ポストベーク、現像を行い、ブレークスルータイムの測定を行った。
