β¦ Synopsis
Electromigration damage is a microscopic phenomenon involving electric field-induced diffusion, which is very relevant to damage in interconnects. Recently, we have developed a novel and useful optical microscopy method with which we can visually observe and record such damage formation during an accelerated stress test. This new noncontact technique provides complementary information to the more traditional probe of electrical resistance.
