摘要： 【課題】Cu合金芯材とその表面に形成されたPd被覆層とを有する半導体装置用ボンディングワイヤにおいて、高温におけるボール接合部の接合信頼性向上と、耐力比(=最大耐力/0.2%耐力):1.1〜1.6の両立を図る。 【解決手段】ワイヤ中に高温環境下における接続信頼性を付与する元素を含むことによって高温におけるボール接合部の接合信頼性を向上し、さらにボンディングワイヤのワイヤ軸に垂直方向の芯材断面に対して結晶方位を測定した結果において、ワイヤ長手方向の結晶方位のうち、ワイヤ長手方向に対して角度差が15度以下である結晶方位 の方位比率を30%以上とし、ボンディングワイヤのワイヤ軸に垂直方向の芯材断面における平均結晶粒径を0.9〜1.5μmとすることにより、耐力比を1.6以下とする。 【選択図】なし

摘要： 表面にPd被覆層を有するCuボンディングワイヤにおいて、高温高湿環境でのボール接合部の接合信頼性を改善し、車載用デバイスに好適なボンディングワイヤを提供する。Cu合金芯材と、前記Cu合金芯材の表面に形成されたPd被覆層とを有する半導体装置用ボンディングワイヤにおいて、ボンディングワイヤがInを0.011〜1.2質量%含み、Pd被覆層の厚さが0.015〜0.150μmである。これにより、高温高湿環境下でのボール接合部の接合寿命を向上し、接合信頼性を改善することができる。Cu合金芯材がPt、Pd、Rh、Niの1種以上をそれぞれ0.05〜1.2質量%含有すると、175℃以上の高温環境でのボール接合部信頼性を向上できる。また、Pd被覆層の表面にさらにAu表皮層を形成するとウェッジ接合性が改善する。
