The first and second layers are disposed on opposite sides of the copper layer and are in direct mechanical contact with the copper layer. The first and second layers each include a same alloy of nickel and a metal consisting of cobalt, iron, copper, manganese, or molybdenum. A first region in the first layer extends completely through the first layer. A second region in the second layer extends completely through the second layer. A third region in the first layer extends completely through the first layer. The third region does not extend into any portion of the second layer. The first, second region, and third regions each include a photoresist or an opening such that photoresist or opening extends completely through the first, second, and first layer, respectively.
