A new failure mechanism of electromigration by surface diffusion of Sn on Ni and Cu metallization in microbumps
Microbumps in three-dimensional integrated circuit now becomes essential technology to reach higher packaging density. However, the small volume of microbumps dramatically changes the characteristics from the flip-chip (FC) solder joints. For a 20 µm diameter microbump, the cross-section area and th...
