Abstract
Description
a)基板を提供することと、
b)銅電気めっき組成物を提供することであって、組成物が、1つ以上の銅イオン源、1つ以上の電解質、1つ以上の促進剤、1つ以上の抑制剤、及び以下の式を有する1つ以上のイミダゾール化合物を含み、
c)銅電気めっき組成物を基板に塗布することと、
d)銅電気めっき組成物を使用して基板上に均一な形態を有する銅を電気めっきすることと、を含む、方法をさらに含む。
TIR=高さ中央−高さ辺
式中、高さ中央は、その中央軸に沿って測定されたピラーの高さであり、高さ辺は、辺上の最高点でその辺に沿って測定されたピラーの高さである。
WID%=1/2x[(高さ最大値−高さ最小値)/高さ平均]×100
式中、高さ最大値は、ピラーの最も高い部分で測定された、基板上に電気めっきされたピラーのアレイの最も高いピラーの高さである。高さ最小値は、ピラーの最も高い部分で測定された、基板上に電気めっきされたピラーのアレイの最も低いピラーの高さである。高さ平均は、基板上に電気めっきされたすべてのピラーの平均の高さである。最も好ましくは、本発明の銅電気めっき組成物及び方法は、平均TIRが0〜3の範囲になるように平均TIRとWID%との間に均衡が存在する基板上にフォトレジストで画定されたフィーチャのアレイを提供し、WID%は、上記に開示されているように各パラメータの好ましい範囲で0%〜16%の範囲である。
銅電気めっき浴
本発明の以下の銅電気めっき浴を、以下の表1に開示される構成成分及び量を用いて調製した。
3,3’−(エタン−1,2−ジイル)ビス(1−(2−ヒドロキシエチル)−1H−イミダゾール−3−イウム)塩化物の合成
20mLの圧力管の中に、N−(2−ヒドロキシエチル)イミダゾール(2.55g、22.7mmol)と1,2−ジクロロエタン(1.00g、10.11mmol)を秤量した。アセトニトリル(10mL)を添加し、チューブを密封し、90℃まで60時間加熱した。室温に冷却し、結果として得られた沈殿物を濾過により単離し、新しいアセトニトリルで洗浄し、真空中で乾燥させ、白色粉末として2.91g(59%)の化合物を得た。
1H NMR(400MHz、DMSO−d6)δ9.37(s、2H)、7.79(s、4H)、5.50(t、J=5.5Hz、2H)、4.81(s、4H)、4.23(t,J=4.6Hz、4H)、3.70(t、J=5.2Hz、4H)。13C NMR(101MHz、DMSO−d6)δ136.96、123.06、122.28、59.08、51.84、48.30。
銅電気めっき浴
本発明の以下の銅電気めっき浴を、以下の表2に開示される構成成分及び量で調製した。
各領域がパターン化されたフォトレジストの50μmの厚さ及び各領域で50μmの直径を有する複数のアパーチャを有する、2つの異なるピッチ領域(密ピッチ=100μm、及び疎ピッチ=250μm)を有する300mmのシリコンウエハダイ(米国ワシントン州バンクーバーのIMAT,Inc.より入手可能)を、実施例1の表1に開示される本発明の銅電気めっき浴に浸漬した。アノードは可溶性銅電極であった。ウエハ及びアノードを整流器に接続し、アパーチャの底部で露出したシード層上に銅ピラーを電気めっきした。めっき中の平均電流密度は15ASDであり、銅電気めっき浴の温度は25℃であった。めっき浴のpHは<1であった。電気めっきの後、次いで、残りのフォトレジストを、Dow Chemical Companyから入手可能なBPRフォトストリップ溶液で剥離し、ウエハダイ上の2つの異なるピッチ領域に銅ピラーのアレイを残した。次いで、各領域からの8つの銅ピラーを、その形態について、5つを密な領域で、3つを疎な領域で分析し、高さ均一性及びTIRの両方についてダイ内で最も大きな変化を捕捉した。銅ピラーの中心及び端部での高さ、ならびにピラーのTIRを、KEYENCE 3D形状解析レーザ顕微鏡VK−Xシリーズを使用して測定した。TIRを、以下の式によって決定した。
TIR=高さ中央−高さ辺
WID%=1/2x[(高さ最大値−高さ最小値)/高さ平均]×100
