Description
[発明1]
レジスト膜上に設けられて、前記レジスト膜を保護するトップコート組成物であって、下記一般式(5)で表される繰返し単位を有する含フッ素重合体を含むことを特徴とするフォトレジスト用トップコート組成物。
[発明2]

[発明5]
有機溶剤を含むことを特徴とする発明1〜4のトップコート組成物。
[発明6]
有機溶剤が炭素数5〜20の環状または鎖状の炭化水素、炭素数1〜20のアルコール、部分的にフッ素で置換された環状または鎖状炭化水素よりなる群より選ばれる1種または2種以上からなる有機溶剤である発明5のトップコート組成物。
[発明7]
有機溶剤が炭素数5〜20の炭化水素を50%以上99.9%未満、炭素数1〜20のアルコールを0.1%以上50%未満で混合した溶剤である発明5または発明6のトップコート組成物。

[発明9]
発明1〜8のいずれかのトップコート組成物から形成された半導体装置製造用のトップコート。
[発明10]
発明9のトップコート組成物を使用して製造した半導体装置。
上記一般式(5)の繰返し単位を有する含フッ素重合体を与える含フッ素重合性単量体は、下記一般式(1)で表すことができる。
上記のように、環に直接結合する水酸基の数は5員環で1〜3、6員環で1〜4の範囲をとりうる。この水酸基は、現像液への溶解性を促進するのに効果的であるが、数が増えるにしたがって現像時に膨潤を引き起こす可能性が大きくなる。溶解性と膨潤の性能のバランスに依存するところもあるが、この水酸基の数は1〜2である方が、3以上の場合よりも好ましい。
「非特許文献3」Basil S.Farah,Everett E.Gilbert,Morton Litt,Julian A.Otto,John P.SibiliaJ.Org.Chem.,1965,30(4),pp 1003-1005
次いで、この中間体の環に水素添加反応して対応する脂環式化合物(アルコール体)に誘導し、更にこれを(メタ)アクリル酸またはその反応性誘導体でエステル化することによって含フッ素重合性単量体を合成することができる。
一般式(5)で表される繰り返し単位は、一般式(1)で表される含フッ素単量体の重合性二重結合が開裂して形成され、その他の構造は維持される。したがって、R1、R2、R3、m、nについての説明およびそれらの組み合わせの具体例は一般式(1)で表される含フッ素単量体についての開示がそのまま適用できる。
分子量分散は1〜4であり、1〜2.5が好ましい。
レジスト膜を浸食しにくく、かつ、レジスト膜から添加物を抽出しにくい有機溶剤としては、下層のレジスト膜組成に依存するが、炭化水素溶媒、アルコール、エーテル、エステル、フッ素系溶剤などが挙げられる。
具体的には好ましくは、ペンタン、ヘキサン、ヘプタン、オクタン、ノナン、デカンなどのアルカンや脂環類の炭化水素溶媒やブタノール(ノルマル、イソ体、ターシャリー)、メチルエチルカルビノール、ペンタノール、アミルアルコール、ヘキシルアルコール、ヘプチルアルコール、4−メチル−2−ペンタノールなどのアルコール類、さらに好ましくは部分的にフッ素で置換された炭化水素系溶媒が好適に採用される。部分的にフッ素で置換された炭化水素溶媒とは、アルカンや脂環類の炭化水素溶媒やアルコール類であって、その水素の一部がフッ素原子で置換されたものが採用できる。フッ素原子を導入することで本発明の高分子化合物を効果的に溶解させ、かつ下地のレジスト膜にダメージを与えないコーティングを行うことが可能となる。
上記の溶媒の中でも、沸点の関係で特定の炭素数の炭化水素、アルコールが好ましい。炭素数が小さすぎると沸点が70℃より低く、炭素数が大きすぎると沸点が170℃を越えてしまいスピンコートには適さない。
かかる溶媒としては、炭素数5〜20のアルカンもしくは脂環類の炭化水素、炭素数1〜20の炭化水素系アルコール、または、上記炭化水素もしくはアルコールが部分的にフッ素原子で置換されたものよりなる群より選ばれる1種の有機溶媒または2種以上の混合溶媒が好ましい。
さらに好ましくは、炭素数5〜10のアルカンまたは脂環類の炭化水素、炭素数1〜10の炭化水素系アルコール、および、これらの炭化水素または炭化水素系アルコールが部分的にフッ素で置換されたものよりなる群より選ばれる1種の有機溶媒または2種以上の混合液が挙げられる。
また、本発明においては、水の膨潤やしみ込みに対する影響を抑制するための疎水性添加剤、現像液への溶解性を促進させるための酸性添加剤などが好適に使用できる。
本発明によるトップコート組成物は、下層のレジストの種類に制限なく使用することができる。すなわち下層レジストが、ネガ型、ポジ型、複合型などの任意のレジストシステムであっても好適に使用できる。
また、特に本発明のトップコート組成物は液浸リソグラフィーにおいて、好適に応用される。
以下、液浸リソグラフィーを用いたデバイス(半導体装置)製造において本発明を使用する場合について説明する。デバイスとしては、特に限定されないが、シリコンウェハー、化合物半導体基板、絶縁性基板などに形成されるCPU、SRAM、DRAMなどの微細加工により製造される半導体装置が挙げられる。

・トップコート組成物配合
重合体合成例1〜5で得られた重合体を用い、それぞれ表2の実施例1〜4、比較例1および比較例2に示す割合で溶剤に溶解して、調製したところ、いずれも均一で透明なトップコート溶液(トップコート−1−1、トップコート−1−2、トップコート−2、トップコート−3、比較トップコート−1、比較トップコート−2)が得られた。
重合体合成例6で得られたレジスト用重合体をプロピレングリコールモノメチルエーテルアセテート(PGMEA)に溶解し、固形分12%に調整した。さらに酸発生剤としてノナフルオロブタンスルホン酸トリフェニルスルホニウムを重合体100重量部に対して5重量部、塩基としてイソプロパノールアミンを同2重量部溶解し、レジスト溶液を調製した。実施例1と同様に、反射防止膜処理したシリコンウェハーに同様な条件で塗布、乾燥を行いレジスト膜を形成した(参考例1)。
トップコート溶液およびレジスト組成物の配合を調整するにあたり、上記のように表2に示した溶剤を用いトップコート溶液およびレジスト組成物を調製した。いずれも、良好な溶解性を示した。結果を表2に示した。
実施例1〜4、比較例1、2で得られた樹脂膜と重合体合成例6から得たレジスト膜について後退接触角を測定した。動的接触角計(協和界面科学社製)の拡張縮小法により、水滴の後退接触角を測定した。初期液滴サイズ7μLを6μL/秒の速度にて8秒間吸引し、吸引中の動的接触角が安定した値を後退接触角とした。結果を表2に示す。
実施例1〜4、比較例1および2で得られた樹脂膜を2.38重量%テトラメチルアンモニウムヒドロキシド水溶液(現像液)に室温で60秒間浸漬したところ、比較トップコート−1を用いた場合(比較例1)を除き、速やかに膜が溶解して消失した。なお、参考例1で得られたレジスト膜について同様に溶解性を測定したところ、未露光であるため膜の溶解は観察されなかった。
参考例1で調製したレジスト溶液、実施例1〜4および比較例1〜2で調製したトップコート溶液を用いて、下記に示すプロセスでシリコンウエハー上にレジスト層とトップコート層の2層膜よりなる樹脂膜を形成した。
参考例1で得られたレジスト溶液を、スピナーを用いてシリコンウェハー上にスピンコート後、ホットプレート上で100℃で90秒間乾燥し、膜厚150nmのレジスト膜を得た。このレジスト膜上に、メンブランフィルター(0.2μm)でろ過したトップコート−1−1の溶液を、スピナーを用いてスピンコート後、ホットプレート上で100℃で90秒間乾燥して、合計膜厚200nmの樹脂膜(レジスト層とトップコート層からなる2層膜)を形成した。
上記の方法で樹脂膜を形成したシリコンウェハー20枚を、それぞれ、20mlの純水に10分浸漬して溶出物を抽出後、当該抽出液をイオンクロマトグラフィにて測定して、溶出物の有無を確認した。トップコートを設けなかったもの(比較例3)を除いて、光酸発生剤やその分解物に帰属されるピークは観測されなかった。これは、トップコートを設けたことにより、レジスト膜からレジスト成分の水への溶出が抑えられてたことを示す。
レジストを塗布して樹脂膜を形成したシリコンウェハーを、レジスト現像アナライザー RDA-790(リソテックジャパン(株)製)を用いて室温でアルカリ現像液(2.38重量%テトラメチルアンモニウムヒドロキシド水溶液)に浸漬して溶解速度を測定した。結果を表3に示した。
レジスト膜上にトップコート溶液を塗布して樹脂膜を形成したシリコンウェハーを、100℃で90秒間プリベークを行った後、フォトマスクを介して193nmで露光した。露光後のウェハーを回転させながら純水を2分間滴下した。その後、120℃で60秒間ポストエクスポーザーベークを行い、アルカリ現像液で現像した。アルカリ現像液としては、2.38重量%テトラメチルアンモニウムヒドロキシド水溶液を用いた。
