摘要： The sputtering target made of a Ag—Bi-base alloy contains Bi in solid solution with Ag. The sputtering target has an intensity of precipitated Bi of 0.01 at %−1 or less, as calculated by the following mathematical expression (1) based on analysis results of X-ray diffraction, and/or a sum of area ratios of predetermined intensities (third to sixth intensities in 8 intensities) of 89% or more, wherein the area ratios are obtained by calculating a planar distribution of characteristic X-ray intensities of Bi according to X-ray microanalysis: intensity of precipitated Bi=[IBi(102)/IAg(111)+IAg(200)+IAg(220)+IAg(311))]/[Bi]. Remarkable lowering of the yield of Bi content in resultant films can be suppressed by using the sputtering target.
摘要翻译：由Ag-Bi基合金制成的溅射靶包含Bi的Bi与Ag的固溶体。溅射靶的沉积Bi强度为0.01at％-1以下，根据X射线衍射的分析结果通过以下数学式（1）计算，和/或预定强度的面积比（ 8个强度的第三至第六强度）为89％以上，其中，通过根据X射线微量分析计算Bi的特征X射线强度的平面分布来获得面积比：沉淀Bi = [IBi（102） / IAg（111）+ IAg（200）+ IAg（220）+ IAg（311））] / [Bi]。通过使用溅射靶可以抑制所得膜中Bi含量的产率的显着降低。

摘要： An Ag sputtering target 6 has three-dimensional fluctuation of grain sizes of not more than 18%. The fluctuation is determined by exposing plural sputtering surfaces by slicing the sputtering target 6 in planes to initial sputtering surface, selecting plural locations on each of the exposed sputtering surfaces, calculating values A1 and B1 using the formula below, and selecting larger one of the values A1 and B1 as the three-dimensional fluctuation of the grain sizes. A1=(Dmax−Dave)/Dave×100(%) B1=(Dave−Dmin)/Dave×100(%) Dmax: maximum value among the grain sizes D at all the selected locations Dmin: minimum value among the grain sizes D at all the selected locations Dave: average value of the grain sizes D at all the selected locations.
