Abstract
【解決手段】紫外線吸収モノマー及び塩基溶解度向上モノマーを含むモノマーの重合によって調製されるコポリマー。本コポリマーからのフィルムキャストは、150〜400ナノメートルの範囲の波長で0.1〜0.5の消衰係数kを有するコポリマー。好ましくは、1.05〜1.2の分散度(Mw/Mn)を有するコポリマー

Description
ポリマー濃度の関数としてのフィルム厚の決定。フォトレジストポリマーCBP−4の構造を表3に示す。一連のフォトレジスト溶液を、溶媒であるエチルラクテートまたは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)中の標的濃度1、2、3、4、及び5重量%のフォトレジストポリマーCBP−4溶液と同様に調製した。代表的なスピンコーティングプロセスは、以下のように実行された。まず、シリコンウェハをアセトン及びイソプロパノールですすいだ。次いで、このシリコンウェハを100℃のホットプレート上に10分間置いた。次いで、このシリコンウェハをO2プラズマ処理によってさらに清浄した。フォトレジスト溶液をシリコンウェハ上に3000回転毎分(rpm)の速度で60秒間スピンコートした。フォトレジスト溶液をウェハ上にコートした後、フォトレジスト層を100℃で90秒間加熱することにより乾燥させて、フォトレジスト層が粘着しなくなるまで溶媒を除去した。フィルム厚をSCI Filmtek 4000分光反射率計上で測定した。フィルム厚対ポリマー濃度の線形曲線を図5(a)に提示する。曲線によれば、約50ナノメートルの所望のフォトレジスト層厚を達成するために、最終ポリマー濃度として2.5〜3重量%が使用された。
混合試験の典型的なプロセスは、以下のように実行された。まず、フォトレジスト溶液をシリコンウェハ上にスピンコートして、50ナノメートルの層を形成した。塗布後ベーク後、フォトレジスト層の厚さを測定した。次いで、トップコート溶液(2−メチル−2−ブタノール中のポリ(PEGMA−co−BzMA−co−HFACHOH))をフォトレジスト層の上にスピンコートした。塗布後ベーク後、総層厚を測定した。「ダークロス(dark loss)」を、現像溶液(2.38重量%TMAH溶液)中にトップコート層を溶解した後に測定し、続いて脱イオン水ですすいだ。「ダークロス」とは、トップコート除去前後のフォトレジスト層厚の差のことであり、測定において露光が伴わないためにダークロスと称される。
接触角測定用の試料調製の典型的な手順は、以下の通りであった。CBP−4フォトレジスト溶液を清潔なシリコンウェハ上にスピンコートした。フォトレジスト層の前に接着促進剤コーティングをウェハ上に適用しなかった。トップコート溶液をフォトレジスト層上にスピンコートし、10または30ナノメートルの厚さを有するトップコート層を形成した。Dataphysics OCA20接触角システムを用いて室温で接触角を測定した。ぬれ挙動の測定を実施するために、脱イオン水滴(2マイクロリットル)を試料表面上に滴下した。
帯域外光に対するトップコート層の遮断効果を調べるために、トップコート薄フィルムの光学特性をVUV VASEエリプソメーターにより測定した。光学定数n及びk、ならびにフィルム厚を、J.A.Woollam(商標)VUV VASE(商標)分光エリプソメーター上で測定した。VUV VASE測定は、波長範囲λ150−1000ナノメートルに相当する1.2〜8.3電子ボルト(eV)のスペクトル範囲、及び一段階につき5°ずつ65°〜75°の入射角を用いて実施した。全光路を乾燥窒素パージの中に包囲して、周囲の水蒸気及び酸素からの吸収を排除した。本研究におけるモデリング及びフィッティングの手順は、まずコーシー(Cauchy)層を使用して300〜1000ナノメートルのスペクトルの透過領域の厚さ及び光学定数を決定すること、次いで光学定数である消衰係数「k」及び屈折率「n」を得るために、逐点法を使用して150〜300nmの範囲にわたる曲線を適合させることからなる。トップコート層の光学特性を、表7にまとめ、図7(波長及びトップコート層厚の関数としての消衰係数)及び図8(波長及びトップコート層厚の関数としてのパーセント透過率)に提示する。表7ならびに図7及び8に示されるように、13及び30ナノメートルの厚さを有するトップコート層では、消衰係数kは、それぞれ0.213及び0.215である。193ナノメートルでの透過率パーセンテージは、それぞれ83.2%及び64%であると計算された。吸収係数αは、13.9及び14.0μm−1であった。
電子ビームリソグラフィ(EBL)用の試料を以下のように調製した。フォトレジストポリマーCBP−4(25ミリグラム)及びトリイソプロパノールアミン(0.20ミリグラム、CBP−4コポリマー中に繰り返し単位を生成する光酸に対して20モルパーセント)を、20ミリリットルのバイアルに入れた。エチルラクテート(760マイクロリットル、786ミリグラム)を添加して、3重量%のCBP−4ポリマー濃度を有する溶液を作製した。トップコートポリマー、ポリ(PEGMA−co−BzMA−co−HFACHOH)(10ミリグラム)を、2−メチル−2−ブタノール(5ミリリットル、4.02グラム)中に溶解して、0.25重量%の濃度を有する溶液を作製した。
図10は、(a)51μC/cm2で露光されたCBP−4フォトレジスト層、(b)53μC/cm2で露光されたCBP−4フォトレジスト層、(c)55μC/cm2で露光されたCBP−4フォトレジスト層、(d)51μC/cm2で露光されたCBP−4フォトレジスト層+10nmトップコート層、(e)57μC/cm2で露光されたCBP−4フォトレジスト層+10nmトップコート層、及び(f)60μC/cm2で露光されたCBP−4フォトレジスト層+10nmトップコート層に関する線パターンの走査電子顕微鏡写真(SEM)を提示する。
