摘要: 本发明提供了一种能够即使在水从半导体器件以外渗透进焊盘之上的开口时仍然阻止在开口的侧表面暴露的氮化钛膜转变成氧化钛膜并且因此提高半导体器件的可靠性的技术和一种能够阻止在焊盘的表面保护膜中出现裂缝并且提高半导体器件的可靠性的技术。形成开口使得开口的直径小于另一开口的直径并且在另一开口中包括该开口。由于这一点,有可能用该开口形成于其中的表面保护膜覆盖在另一开口的侧表面暴露的防反射膜的侧表面。由于这一点,有可能形成焊盘而不暴露防反射膜的侧表面。

摘要: 一种铜或铜合金,其特征在于,α射线量为0.001cph/cm2以下。最近的半导体器件具有高密度化和高容量化,因此,受到来自于半导体芯片附近的材料的α射线的影响而发生软错误的危险增多。特别是,对于靠近半导体器件使用的铜或铜合金布线、铜或铜合金接合线、焊锡材料等的铜或铜合金的高纯度化的要求强烈,而且寻求α射线少的材料,因此,本发明的课题在于阐明铜或铜合金的α射线产生的现象并且得到能适应于所要求的材料的使α射线量降低后的铜或铜合金及以铜或铜合金作为原料的接合线。
