| 摘要 |
The present invention relates to a silver alloy bonding wire containing silver (Ag) as a main component, palladium (Pd), and gold (Au), and, more specifically, to an alloy bonding wire in which the palladium (Pd) content is 0.1 to 0.4 wt% and the weight content ratio of gold (Au) to palladium (Pd) is 0.25 to 1.0. The use of the silver alloy bonding wire of the present invention can improve the ball shape uniformity and the bonding ball shape of a ball which is formed on the tip of a wire and provide excellent reliability, loop linearity, and binding strength. |
