摘要: 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、175℃〜200℃のHTSでの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。ワイヤ中にNi、Zn、Rh、In、Ir、Ptの1種以上を総計で0.03〜2質量%含有することによってHTSでの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50%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0.9〜1.3μmとすることにより、耐力比を1.6以下とする。

摘要: The invention is aimed at providing a bonding structure of a copper-based bonding wire, realizing low material cost, high productivity in a continuous bonding in reverse bonding for wedge bonding on bumps, as well as excellent reliability in high-temperature heating, thermal cycle test, reflow test, HAST test or the like. The bonding structure is for connecting the bonding wire onto a ball bump formed on an electrode of a semiconductor device, the bonding wire and the ball bump respectively containing copper as a major component thereof. The bonding structure comprises a concentrated layer A provided at an interface of a bonding part of the ball bump and the bonding wire, wherein the concentration of a metal R other than copper in the concentrated layer A is not less than ten times the average concentration of the metal R in the ball bump; and a concentrated layer B provided at an interface of a bonding part of the ball bump and the electrode, wherein the concentration of the metal R in the concentrated layer B is not less than ten times the average concentration of the metal R in the ball bump.
