摘要: Cu合金芯材の表面にPdを主成分とする被覆層と、該被覆層の表面にAuとPdを含む表皮合金層を有する半導体装置用ボンディングワイヤであって、Pdめっきリードフレームでの2nd接合性をさらに改善するとともに、高湿加熱条件においても優れたボール接合性を実現することのできるボンディングワイヤを提供する。Cu合金芯材の表面にPdを主成分とする被覆層と、該被覆層の表面にAuとPdを含む表皮合金層を有する半導体装置用ボンディングワイヤにおいて、ワイヤ最表面におけるCu濃度を1〜10at%とし、芯材中に元素周期表第10族の金属元素を総計で0.1〜3.0質量%の範囲で含有することにより、2nd接合性の改善と、高湿加熱条件における優れたボール接合性を実現することができる。さらに、表皮合金層のAuの最大濃度が15at%〜75at%であると好ましい。
