Zusammenfassung: | A silver (Ag) alloy bonding wire according to the technical spirit of the present invention comprises: about 1 to 20 wt% of a first additive element; about 3 to 100 wt ppm of a second additive element; and the remainder consisting of silver (Ag). The first additive element is gold (Au), palladium (Pd), or an alloy thereof. The second additive element is at least one selected from the group consisting of calcium (Ca), lanthanum (La), beryllium (Be), germanium (Ge), nickel (Ni), bismuth (Bi), yttrium (Y), manganese (Mn), tin (Sn), iron (Fe), copper (Cu), and magnesium (Mg). The silver (Ag) alloy bonding wire according to the present invention has an elongation of about 15 to 25% and a Youngs modulus of about 60 to 80 GPa. The silver (Ag) alloy bonding wire according to the present invention can reduce manufacturing costs and improve bonding characteristics by using a silver (Ag) alloy.
