    • PROBLEM TO BE SOLVED: To provide high-purity tin or a tin alloy which is used, such as for manufacturing recent semiconductor devices with increased density and increased capacity, for which increased purity is strongly demanded, and in which α-ray dosage of tin is reduced.SOLUTION: High-purity tin includes U and Th with respective contents of 5 ppb or less and Pb and Bi with respective contents of 1 ppm or less, and has a purity of 5N or higher (provided that the gas components of O, C, N, H, S and P are excluded). A high-purity tin alloy includes an additive alloy element having a purity equal to or higher than that of the high-purity tin, and a purity of an alloy obtained from the high-purity tin and the additive alloy element is 5N or higher (provided that the gas components of O, C, N, H, S and P are excluded). An α-ray count of a tin ingot obtained by casting the tin or the tin alloy satisfies 0.001 cph/cm2 or less after the lapse of 6 months or longer.
    • 要解决的问题:提供使用的高纯度锡或锡合金,例如用于制造近来具有增加的密度和增加的容量的半导体器件,其中强烈要求增加纯度,并且其中α射线用量的锡 降低了成分。溶液:高纯度锡包括U和Th,各自含量为5ppb以下,Pb和Bi的含量为1ppm以下,纯度为5N以上(条件是气体成分为O ,C,N,H,S和P)。 高纯度锡合金包括纯度等于或高于高纯度锡的添加合金元素,由高纯度锡和添加合金元素获得的合金的纯度为5N以上( 条件是排除O,C,N,H,S和P的气体成分)。 通过铸造锡或锡合金得到的锡锭的α射线计数在经过6个月以上时满足0.001cph / cm 2以下。
