  • Publication number: 20170256517
    Abstract: A bonding wire and a method of manufacturing the bonding wire are provided. The bonding wire contains 90.0 to 99.0 wt % of silver (Ag); 0.2 to 2.0 wt % of gold (Au); 0.2 to 4.0 wt % of palladium (Pd), platinum (Pt), rhodium (Rh), or a combination thereof; 10 to 1000 ppm of dopants; and inevitable impurities. In the wire, the ratio of (a)/(b) is 3 to 5, in which (a) represents the amount of crystal grains having <100> orientation in crystalline orientations <hkl> in a wire lengthwise direction and (b) represents the amount of crystal grains having <111> orientation in crystalline orientations <hkl> in the wire lengthwise direction.
