- l having good wettability of l: 30at%, V, Cr, Al, Si, Ti,
- Ni-Cu alloy system consisting of the balance of Ni and unavoidable impurities
- At least one or more elements selected from V, Cr, Al, Si, Ti, and Mo, the curative point of Ni, which is a ferromagnetic material, is reduced linearly by the addition of 2 to 25 at% of calorie. It became possible to make it magnetic.
- Ni is a material having good solder wettability. To some extent, it also has a function as a solder diffusion barrier. However, there was a problem that magnetron sputtering was extremely difficult because of the ferromagnetic material!

- the addition of 110 at% of Cu to Ni has a function of preventing the diffusion of Sn. Since Cu has higher reactivity with Sn than Ni, a layer of a Cu—Sn intermetallic compound (Cu Sn, Cu Sn) is formed between the Cu and the solder by heat treatment. This layer acts as a diffusion barrier
- the effect of suppressing the diffusion of Sn by such a Ni-Cu alloy-based barrier layer is that Sn is already saturated in the Ni-Cu film as the intermediate barrier, so that the Pb-free Sn-based solder bump or the Sn- It is considered that Sn movement and diffusion of Pb-based solder bumps are prevented. If the Cu—Sn intermetallic compound layer is too thick, cracks are liable to occur, causing solder to fall off or peel off. On the other hand, if it is too thin, it will lose its function as a barrier layer.
- the Ni—Cu alloy-based noria layer has a feature that the wettability with the Pb-free Sn-based solder bump or the Sn—Pb-based solder bump is extremely good.
- Ni-Cu-based alloy barrier layer As a component of a nickel alloy sputtering target for forming a Ni-Cu-based alloy barrier layer, Cu: 1-30at% is required.
- Cu—Sn intermetallic compound Cu Sn
- the effect as a diffusion barrier cannot be exhibited.
- the content of Cu exceeds 30 at%, the thickness of the Cu-Sn intermetallic compound layer becomes thicker, and cracks are easily generated. Therefore, the content of Cu must be 30 at% or less.
- the amount of one or more elements of V, Cr, Al, Si, Ti, and Mo in the Ni—Cu alloy of the present invention needs to be 2 to 25 at%. If the amount of soybean curd is less than 2 at%, the curry point will not be sufficiently reduced.
