題目：From Electromigration to Novel Electro-treatment of Materials: Introductions to the Theories and Applications
內容摘要：
Electric current stressing of materials has a long history, and researchers have been devoted to investigating the unique electron wind force effects. Current-assisted mass transport induces the migration of atoms which is called “electromigration.” Electromigration resulting from the electron wind force is an inevitable phenomenon that will cause the failure occurrence in metallic interconnects in electronic devices after a long-term current stressing. However, we introduce herein a material treatment approach that takes advantage of the “athermal” electron wind force that can produce high-density dislocations in metals and the accompanying “thermal” Joule heating effect for inducing the subsequent recrystallization process. The interaction between dislocations and electron wind, the fundamental of the current-assisted treatment or “electro-treatment,” is the basic theory applied for the microstructure and properties manipulation. Electro-treatment as proposed is expected to be a potential approach with high-efficiency and low-energy consumption features for replacing post-working heat treatment of metals. This presentation will give basic introductions to the theories and applications from electromigration aspect to electro-treatment aspect.
