  • Publication number: 20170259366
    Abstract: In a lead-free solder bump, diffusion of Cu from intermetallic compound layers, which are respectively formed at joining interfaces with Cu electrodes is suppressed, so that the in metallic compound layers are not likely to disappear. Correspondingly, with the use of the intermetallic compound layers, Cu is not likely to diffuse from the Cu electrodes into the lead-free solder bump. Even when an electric current flows continuously between a first electronic member and a second electronic member through the lead-free solder bump, the occurrences of the electromigration phemenon and the thermomigration phenomenon are suppressed. Thus, the present invention provides a lead-free solder bump joining structure capable of suppressing the disconnection failure caused by the synergistic effect of the electromigration phenomenon and the thermomigration phenomenon.
