Investigation of grain growth mechanisms in nanocrystalline Cu for Cu direct bonding

Cu direct bonding technology is a critical approach for achieving highly integrated packaging structures. Recent studies demonstrate that utilizing nanostructured Cu enables a significant reduction in Cu–Cu bonding temperature, where nanoscale grain growth plays a crucial role. However, the thermody...
