Description
本出願は2004年6月15日に出願した米国仮出願第60/580,001号の優先権を主張する。
マイクロエレクトロニクス構造を製造するには多くの工程を伴う。集積回路の製造スキームでは、半導体表面の選択エッチングが時折必要である。歴史的には、材料を選択的に除去するための多くの非常に異なるタイプのエッチング法は種々の程度でうまく用いられてきた。さらに、マイクロエレクトロニクス構造内での異なる層の選択エッチングは集積回路製造方法における重要でかつ重大な工程と考えられている。
ここに開示される組成物は、組成物に暴露されうる金属、低k誘電体及び/又は高k誘電体材料を望ましくない程度に攻撃することなく、たとえば、フォトレジスト、ギャップフィル、BARC及び/又は他のポリマー材料、及び/又は無機材料などの残留物及び処理残留物を基材から選択的に除去することができる。特定の態様において、ここに開示される組成物は暴露時に銅を最小にしか腐食させることなく、有効に残留物を除去することができる。
を含む、組成物が提供される。
を含み、水溶性アミンを実質的に含まない、組成物が提供される。
残留物、たとえば、フォトレジスト、ギャップフィル、ボトム耐反射性コーティング(BARC)及び他のポリマー材料及び/又はエッチングにより生じる残留物などの処理残留物を選択的に除去するための組成物及びそれを用いた方法がここに開示される。マイクロエレクトロニクスデバイスに有用な基材を伴う清浄化方法において、除去されるべき通常の汚染物としては、たとえば、有機化合物、例えば、露光した及び/又はアッシングしたフォトレジスト材料、アッシングしたフォトレジスト残留物、UV−又はX−線硬化したフォトレジスト、C−F含有ポリマー、低及び高分子量ポリマー及び他の有機エッチ残留物、無機化合物、例えば、金属酸化物、ケミカルメカニカル平滑化(CMP)スラリーからのセラミック粒子及び他の無機エッチ残留物、金属含有化合物、例えば、オルガノメタリック残留物及び金属有機化合物、イオン性及び中性の軽量及び重量の無機(金属)種、湿分及び平滑化及びエッチングプロセスなどの処理により生じる粒子を含む不溶性材料が挙げられる。1つの特定の態様において、除去される残留物は反応性イオンエッチングにより形成されるような処理残留物である。
を含むことができる。式(I)及び(II)を有するメルカプト含有腐食抑制剤は、メルカプト有機化合物、例えば、メルカプトアルカン、メルカプトアルカノール、メルカプトアルカンジオール及びメルカプト芳香族化合物を含む。ある態様において、メルカプト含有腐食抑制剤は、2−メルカプト−5−メチルベンズイミダゾール、2−メルカプトチアゾリン、3−メルカプト−1,2−プロパンジオール、3−メルカプトプロピルトリメトキシシラン及びそれらの混合物を含んでよい。別の態様において、ここに開示される組成物は実質的に水溶性アミンを含まず、又は、組成物のストリッピング及び清浄化能力に悪影響を及ぼす又は下地基材の1つ以上の表面を損傷するいかなる追加の成分をも含まない。基材が、とりわけ、銅を含む態様では、組成物は5Å/分未満の銅エッチ速度を示す。
低kのシリコンオキシド含有誘電体フィルム及び多層相互接続のためにエッチングされたフォトレジストパターンを有するシリコンウエハ試験基材をプラズマエッチングプロセスを用いてエッチングした。その後、表Iに与えた種々の例示の組成物及び比較組成物中に表IIに記載した温度及び時間、基材を浸漬することで基材を処理した。走査型電子顕微鏡(SEM)を用いてクリーニング性能を評価した。クリーニング性能結果を表IIに示す。表IIに示した結果は例示の配合物1A及び1Bが有効にフォトレジストをクリーニングできることを示す。
例2はプラズマエッチング後のシリコンウエハ基材からギャップフィルやBARCなどのポリマー材料を除去することについての種々の例示の組成物の有効性を示す。低kのシリコンオキシド含有誘電体フィルム、BARC層及び多層相互接続のためにエッチングされたフォトレジストパターンを有するシリコンウエハ試験基材をプラズマエッチングプロセスを用いてエッチングした。その後、表IIIに与えた種々の例示の組成物及び比較組成物中に表IVに記載した温度及び時間、基材を浸漬することで基材を処理した。SEMを用いてクリーニング性能及び下地のインターレベル誘電体層(ILD)に対する損傷を評価し、結果を表IVに示す。結果は例示の配合物、特に組成物2B及び2CがILD層を攻撃することなくギャップフィル又はBARC材料を有効にクリーニングできることを示す。
例3は、金属フィルムが被覆された基材を種々の時間にわたって比較組成物及び例示組成物に暴露したときに、金属フィルムに対して呈する金属腐食度を示す。シリコンオキシドウエハ基材上に銅フィルムをスパッタリングした。ウエハ上の銅フィルムの初期厚さをCDEResMap 273Four Point Probeを用いて測定した。初期厚さを決定した後に、表Vに示した組成物中に表VIに示した温度で5,10,20,40及び60分間、試験基材を浸漬した。各時間での浸漬の後に、各組成物から試験基材を取り出し、脱イオン水で3分間すすぎ、窒素下で完全に乾燥した。厚さ測定値を各時間で決定し、各例示の組成物の結果に対して「最小二乗法」モデルを用いてグラフ化した。各組成物の「最小二乗法」モデルの計算された傾きはオングストローム/分(Å/分)で示す得られたエッチ速度である。浸漬時間に対する厚さ変化についての直線回帰である銅エッチ速度を用いる。エッチ速度(ER)の要約を表VIに示す。表VIは、比較例3A〜3Dの例示の組成物を比較したときに、例示の組成物、特に、例3B〜3Fは実質的に低い銅エッチ速度を示したことを表している。
