Patent ID: 8785790

Claim:
A component, comprising: a support structure having first and second spaced-apart and parallel surfaces and a plurality of conductive elements extending in a direction between the first and second surfaces, each conductive element containing an alloy of a wiring metal selected from the group consisting of copper, aluminum, nickel and chromium, and an additive selected from the group consisting of Gallium, Germanium, Indium, Selenium, Tin, Sulfur, Silver, Phosphorus, and Bismuth, the alloy having a composition that varies with distance in at least one direction across the conductive element, the at least one direction being substantially parallel to the first and second surfaces of the support structure; wherein a concentration of the additive is less than or equal to 5% of the total atomic mass of the conductive element, and wherein a resistivity of the conductive element is between 2.5 and 30 micro-ohm-centimeters.
