Abstract: With the continuous increasing of function and feature size of heterogeneous integration modules, three-dimensional (3D) integration technology has emerged. The interconnection between bumps is the key to realize 3D stacking of chips, and the preparation of highly reliable micro bumps is of great significance for the further development of microelectronic packaging technology. This review summarized the bump technology in advanced packaging, including bump preparation methods and materials, microstructure and mechanical properties, electrical properties and reliability, and the application of simulation in bumps, providing reference for subsequent research on bumps. Finally, the projection technology will continue to develop towards miniaturization, small pitch, lead-free and high reliability.

Key words: advanced packaging, bump, high reliability
