Description
他の実施態様において、半導体リソグラフィーの応用は、一般的に、パターンを半導体基板上の材料層に転写することを含んでいる。半導体基板の材料層は、金属導電体層、セラミック絶縁体層、半導体層または製造プロセスの段階および最終製品に予定されている所望の材料に応じた他の材料でありうる。本発明の組成物は、好ましくはパターン化される材料層の上に直接、好ましくはスピンコーティングにより塗布される。組成物は、次いで、加熱されて、溶媒が除去され、組成物が硬化(架橋)される。放射線感受性レジスト層が、次いで、本発明の硬化された反射防止組成物の上に、(直接または間接に)塗布されうる。
工程1
4−アセトキシスチレン(16グラム、0.10モル)、トリス(トリメチルシリル)シラン(25グラム、0.10モル)、およびヘプタン100mlを、水冷却器および窒素導入口を備えた丸底フラスコ中に入れた。キシレン(1ml)中の白金(0)−1,3−ジビニル−1,1,3,3−テトラメチルジシロキサン錯体をこの溶液に加え、18時間加熱還流した。その後、溶媒を大気圧で留去し、そして残渣を減圧下で分留して、4−アセトキシ−1−[2−トリス(トリメチルシリル)シリルエチル]ベンゼン(11.0グラム)を透明液体として、5mm圧で190〜215℃の間で集めた。
工程1からの生成物に、メタノール(50ml)および水酸化アンモニウム(水中の30%溶液、2.8ml、0.05モル)を加え、その混合物を2時間、穏やかに加熱還流した。大部分の溶媒をロータリーエバポレーター中で除去し、残渣をエーテル50ml中に溶解した。このエーテル溶液を2x100mlの5%塩酸溶液、続いて100mlの食塩水で洗浄した。次いで、溶液を無水硫酸マグネシウムで乾燥した。その後、ロータリーエバポレーター中で溶媒を除去し、減圧下に乾燥して、8グラムの4−ヒドロキシ−1−[2−トリス(トリメチルシリル)シリルエチル]ベンゼンをワックス状の固体として得た。
ノボラックシランポリマーを以下の手順に従って合成した。実施例1で合成された、5.05gの量の4−ヒドロキシ−1−[2−トリス(トリメチルシリル)シリルエチル]ベンゼンを、機械的攪拌器と還流冷却器を備えたフラスコ中で、1.28gの37.17%ホルマリンと7.5gのメトキシプロパノールと混合した。シュウ酸二水塩(46mg)をその反応混合物に95℃で攪拌しながら加えた。18時間攪拌した後、温度を120℃に上げ、反応混合物を、系にアルゴンを吹き込みながら、120℃で3.5時間加熱した。次いで、ポンプで真空にしながら、浴温を徐々に145℃に上げて、溶媒、未反応のホルマリンおよび水を除去した。得られたノボラックシランポリマーは、ポリスチレンを標準とするゲル透過クロマトグラフィー(GPC)で測定して、2,560の重量平均分子量を有していた。
実施例2で合成されたノボラックシランポリマーをプロピレングリコールモノメチルエーテルアセタート(PGMEA)に100重量部の濃度で溶解した。8重量部の濃度のDayChemから入手できる架橋剤テトラメトキシメチルグリコールウリルおよび4重量部の濃度のジ(t−ブチルフェニル)ヨードニウムペルフルオロブチルスルホナート(DtBPI−PFBuS)をその溶液に加え、10重量%の全固形分を達成した。配合された溶液を、215℃で60秒ホットプレート上で焼付けしたシリコンウエハー上にスピンコーティングし、次いで、nおよびk値を、J.A. Woollam Co. Inc. 製のVB−250VASE偏光解析器で測定した。193nm放射線に対するフィルムの光学特性は以下のとおりである。

ノボラックシラン 1.71 0.34
ノボラックシランポリマーを、FEOLエッチング器上で、Cl2系プラズマ中でエッチングした。HBrおよびCl2系プラズマは一般にシリコンおよびポリシリコンをエッチングするために使用される。下記の表において、ノボラックシランポリマーが典型的な193nmレジストであるAR237Jよりもより低いエッチング速度を有し、シリコンエッチングに対するより良いハードマスクであることを示していることを見ることができる。

ノボラックシランポリマーは約29重量%のSiを有し、そして酸化性(例えば、O2およびSO2−O2)プラズマエッチング並びに還元性プラズマエッチング(N2−H2およびNH3)中で最小のエッチング速度を有することが期待される。そのプラズマは、ノボラックシランがマスクとして使用されて有機下層がパターン化される、三層パターン化スキームに関して使用することができる。3つのSi含有材料について行われたエッチング速度試験の結果を下表に示す。
