    摘要: Disclosed is a nickel layer formed on a substrate by sputtering, in which nickel layer a percent ratio of an X-ray diffraction peak intensity of the (200) plane of the nickel layer to that of the (111) plane of the nickel layer is not less than 10%. This nickel layer has a reduced stress, and therefore, lessens a bending of a substrate. The nickel layer is formed by a process for sputtering nickel on a substrate, comprising supplying an argon gas into a vacuum chamber, adjusting a pressure of the argon gas in the vacuum chamber to a predetermined value, ionizing the argon gas, bombarding a target containing nickel with the ionized argon gas, to sputter nickel atoms, and depositing the sputtered nickel atoms onto the substrate, wherein the predetermined pressure of the argon gas is not lower than 12 mTorr.
