Sputtering target comprising Niamp;#x2014;P alloy or Niamp;#x2014;Ptamp;#x2014;P alloy and production method therefor

摘要

A method of producing a Ni—P alloy sputtering target, wherein a Ni—P alloy having a P content of 15 to 21 wt % and remainder being Ni and unavoidable impurities is melted and atomized to prepare a Ni—P alloy atomized powder having an average grain size of 100 μm or less, the Ni—P alloy atomized powder is mixed with a pure Ni atomized powder, and the obtained mixed powder is hot pressed. An object of the present invention is to provide a method of producing a Ni—P alloy sputtering target which achieves a small deviation from an intended composition.
