ABSTRACT:
A high purity Ni—V alloy, high purity Ni—V alloy target and high purity Ni—V alloy thin film wherein the purity of the Ni—V alloy excluding Ni, V and gas components is 99.9 wt % or higher, and the V content variation among ingots, targets or thin films is within 0.4%. With these high purity Ni—V alloy, high purity Ni—V alloy target and high purity Ni—V alloy thin film having a purity of 99.9 wt % or higher, the variation among ingots, targets or thin films is small, the etching property is improved, and isotopic elements such as U and Th that emit alpha particles having an adverse effect on microcircuits in a semiconductor device are reduced rigorously. Further provided is a method of manufacturing such high purity Ni—V alloys capable of effectively reducing the foregoing impurities.
