Abstract

Cu-Cu direct bonding under help of direct immersion gold (DIG) for multi-die fan-out wafer level package was demonstrated. Cu-Cu direct bonding is a critical technology for high-frequency applications. To solve challenges of conventional methods, the DIG was used. As a result, a cohesion failure was obtained in shear test.
