実施例1~実施例4及び比較例1~比較例2で調製されたレジスト下層膜(保護膜)形成組成物のそれぞれをスピンコーターにてシリコンウエハー上に塗布(スピンコート)した。塗布後のシリコンウエハーをホットプレート上で220℃、1分間加熱し、膜厚100nmの被膜(保護膜)を形成した。次に、保護膜のレジスト溶剤耐性を確認するため、保護膜形成後のシリコンウエハーを、プロピレングリコールモノメチルエーテルとプロピレングリコールモノメチルエーテルアセテートとを重量比7対3で混合した溶剤に1分間浸漬し、スピンドライ後に100℃、30秒間ベークした。混合溶剤を浸漬する前後の保護膜の膜厚を光干渉膜厚計(製品名:ナノスペック6100、ナノメトリクス・ジャパン株式会社製)で測定した。
塩基性過酸化水素水への耐性評価として、実施例1~実施例4及び比較例1~比較例2で調製されたレジスト下層膜形成組成物(保護膜形成組成物)のそれぞれを50nm膜厚の窒化チタン(TiN)蒸着基板に塗布し、220℃、1分間加熱することで、膜厚100nmとなるように保護膜を成膜した。次に、28%アンモニア水、33%過酸化水素、水をそれぞれ重量比1対4対20となるように混合し、塩基性過酸化水素水を調製した。前記のレジスト下層膜形成組成物(保護膜形成組成物)を塗布したTiN蒸着基板を50℃に加温したこの塩基性過酸化水素水中に浸漬し、浸漬直後から保護膜が基板から完全に剥離するまでの時間(剥離時間)を測定した。塩基性過酸化水素水への耐性試験の結果を表2に示す。尚、剥離時間が長くなるほど、塩基性過酸化水素水を用いたウエットエッチング液への耐性が高いと言える。
エッチング選択比の評価として、前記の実施例1~実施例4及び比較例1で調製されたレジスト下層膜形成組成物(保護膜形成組成物)のそれぞれをシリコンウエハー上に塗布し、220℃、1分間加熱することで、膜厚100nmとなるように保護膜を成膜した。次に、成膜した保護膜をドライエッチング装置(製品名:RIE-10NR、サムコ株式会社製)を用い、塩素ガス、及び窒素ガスと水素ガスの混合ガスによるドライエッチングを行うことで、保護膜のドライエッチング速度の比(ドライエッチング速度の選択比)を測定した。エッチング選択比の測定結果を表3に示す。尚、エッチング選択比が大きくなるほど、ドライエッチング速度が速いと言える。
本明細書に記載の実施例1~実施例3及び比較例1~比較例2で調製されたレジスト下層膜形成組成物(保護膜形成組成物)を、それぞれスピンコーターにてシリコンウエハー上に塗布(スピンコート)した。塗布後のシリコンウエハーをホットプレート上で220℃、1分間加熱し、保護膜形成組成物(膜厚100nm)を形成した。そして、これらの保護膜形成組成物を分光エリプソメーター(製品名:VUV-VASE VU-302、J.A.Woollam社製)を用い、波長193nmでのn値(屈折率)及びk値(減衰係数又は吸光係数)を測定した。光学パラメーターの測定結果を表4に示す。
昇華物量の測定は国際公開第2007/111147号パンフレットに記載されている昇華物量測定装置を用いて実施した。まず、直径4インチのシリコンウエハー基板に、実施例1~実施例3、比較例1~比較例2で調製したレジスト下層膜形成組成物をスピンコーターにて、膜厚100nmとなるように塗布した。レジスト下層膜が塗布されたウエハーをホットプレートが一体化した前記昇華物量測定装置にセットし、120秒間ベークし、昇華物をQCM(Quartz Crystal Microbalance)センサー、すなわち電極が形成された水晶振動子に捕集した。QCMセンサーは、水晶振動子の表面(電極)に昇華物が付着するとその質量に応じて水晶振動子の周波数が変化する(下がる)性質を利用して、微量の質量変化を測定することができる。
得られた周波数変化を、測定に使用した水晶振動子の固有値からグラムに換算し、レジスト下層膜が塗布されたウエハー1枚の昇華物量と時間経過との関係を明らかにした。尚、最初の60秒間は装置安定化のために放置した(ウエハーをセットしていない)時間帯であり、ウエハーをホットプレートに載せた60秒の時点から180秒の時点までの測定値がウエハーの昇華物量に関する測定値である。当該装置から定量したレジスト下層膜の昇華物量を昇華物量比として表5に示す。尚、昇華物量は比較例1の値を1と換算し示す。
50nmトレンチ(L(ライン)/S(スペース))を形成したシリコン基板に、CVD法にてシリコン酸化膜を20nm程度堆積させて作製した、シリコン酸化膜がトレンチ表面部に形成されたシリコン加工基板(シリコン酸化膜堆積後:10nmトレンチ(L(ライン)/S(スペース))上に、レジスト下層膜形成組成物を塗布した。その後、ホットプレート上で220℃1分間加熱し、レジスト下層膜を膜厚約100nmで形成した。走査型電子顕微鏡(SEM)を用いて、実施例2で得たレジスト下層膜形成組成物を塗布したトレンチを有する基板の断面形状(図1)を観察することにより、埋め込み性を評価した。実施例のレジスト下層膜形成組成物においては、シリコン酸化膜の間隙である10nmトレンチ(L(ライン)/S(スペース))基板へ、該組成物がボイド(空隙等)を生じることなく埋め込まれていることが分かる(図2)。
