Feinstdraht aus einer Gold-Legierung, Verfahren zu seiner Herstellung und seine Verwendung.

摘要

A fine wire made of an alloy of gold which contains 0.6 to 2 weight % of nickel, or an alloy of gold which contains 0.1 to 2 weight % of nickel, 0.0001 to 0.1 weight % of alkaline earth metal and/or rare earth metal, and optionally 0.1 to 1.0 weight % of platinum and/or palladium . The fine wire is distinguished by a favorable electrical conductivity and a good ratio of strength to elongation. The fine wire is suitable both for wire bonding of semiconductor devices and for producing the ball bumps of flip-chips.
