摘要
Room-temperature electromigration occurs in a thin stripe of eutectic SnPb solder stressed by a current density of 10(5) amp/cm(2). Hillocks and voids grow at the anode and the cathode, respectively. While the dominant diffusion species is Sn in this two-phase alloy, the growth of the hillocks, surprisingly, originates from the Pb grains. (C) 1999 American Institute of Physics.
