摘要: 本发明涉及用于半导体装置中的连接的铜-铂合金线。在用于球焊的铜线中,改善二次接合性、防止球焊中的芯片破裂以及改善成环性能。在通过将熔融的含有高纯度铜(Cu)、包含0.1至2.0质量%的铂(Pt)以及作为非金属元素的1至10质量ppm的硫(S)和10至150质量ppm的氧(O)及必要时1至5质量ppm的磷(P)的铜-铂合金连续铸造而制备元素线的过程中,不含铂的非常薄的铜层由于偏析而形成,并随后在大气中被氧化而在连续拉丝后的线表面层上形成6至2nm的氧化物膜。作为具有77至105Hv维氏硬度的接合线,均匀的氧化物膜改善了二次接合性,且向基体中添加的元素抑制了球焊期间的动态强度,由此防止了铝飞溅,并且保持了不导致倾斜的静态强度。

摘要: 一种金合金键合丝,其特征在于按重量计含有:钯1-1.5%,银20-24%,钙、铍和铈中的一种和其中多种的组合2-200 ppm,余量为金。本发明还提供上述金合金键合丝的一种制造方法。本发明的金合金键合丝可用于IC、LED封装中,综合打线性能优异,具体体现在:热影响区长度小(可达到53-60 um),极大地降低了打线的弧高;烧球性能好,在FAB烧球后得到数目适中的对称柱状晶,变形球真圆度高;封装后产品热冲击性能好,可靠性高。
