Abstract

Abstract

En 中文
• High temperature induced stress concentration by softening substrate, causing semiconductor cracking. • Thermo-mechanical action forms Au-In liquid and drives its flow, resulting in substrate debonding. • The proposed micro-joining method is based on liquid-solid interdiffusion with epitaxial growth. • The strategy enables intermetallic-free, defect-free interfaces and avoids thermo-mechanical damage.
