(3)炭素数が1以上4以下の飽和カルボン酸を0.01mol/L以上2.0mol/L以下含むことを特徴とする前記(1)又は(2)記載のULSI微細ダマシン配線埋め込み用電気銅めっき水溶液。
(4)前記カルボン酸が酢酸であることを特徴とする前記(3)記載のULSI微細ダマシン配線埋め込み用電気銅めっき水溶液。
(5)前記(1)〜(4)のいずれか一項に記載のULSI微細ダマシン配線埋め込み用電気銅めっき水溶液を用いることを特徴とするULSI微細ダマシン配線用電気銅めっき方法。

pHが1.8未満であると、pHが低いため銅シード層が溶解し易くなり、その結果ボイドも発生し易くなる。また、pHが3.0よりも大きい場合、めっき液中の銅イオンが酸化物あるいは水酸化物となって、沈殿が発生する恐れがある。
カルボン酸はめっき液中、0.01〜2.0mol/L含有されることが好ましく、より好ましくは0.2〜1.0mol/Lである。めっき液中のカルボン酸の濃度は埋め込み性、及びpHに影響し、カルボン酸の濃度が2.0mol/Lを超えるとめっき液のpHが1.8未満まで下がり、ボイドが発生し易くなる。また、カルボン酸のめっき液中の濃度が0.01mol/L未満であると、めっき液のpHが3.0を超え、上述のように沈殿が発生する恐れがある。
銅塩としては、硫酸銅、硝酸銅、塩化銅などが挙げられ、硫酸銅が好ましい。銅塩はめっき液中0.05〜1.5mol/L含有されることが好ましく、より好ましくは0.2〜0.8mol/Lである。
塩素イオン濃度はめっき液中0.3〜3.0mmol/L含有されることが好ましく、より好ましくは1.0〜2.0mmol/Lである。
促進剤としては二硫化ビス(3−スルホプロピル)二ナトリウム、3−メルカプトプロパンスルホン酸等が挙げられ、めっき液中1〜30mg/L含有されることが好ましい。
抑制剤としては、ポリエチレングリコール、ポリプロピレングリコール、及びこれらの共重合体等が挙げられ、めっき液中10〜500mg/L含有されることが好ましい。
平滑剤としては、ヤヌスグリーンB、ポリエチレンイミン、ポリビニルピロリドン等が挙げられ、めっき液中0.1〜50mg/L含有されることが好ましい。
銅シード層は、スパッタ法、無電解めっき法等の公知の方法で形成されたものでよい。
本発明の電気銅めっき液を用いてめっきを行うことにより、トレンチ・ビア内の銅シード層の厚さが2nm、又はそれ以下であっても、ボイドが発生することなくめっきすることができる。
