Diffusional processes, either solid- or liquid-state, are essential in promoting reliable metallurgical interconnections used in many electronicpackaging applications. The same phenomena often degrade the integrity and reliability of the interconnections as well. In this talk, both examplesare presented to illustrate how the diffusional processes are important in many interconnection technologies. Thermocompression bonding, eutecticbonding, soldering and liquid-phase bonding are chosen for this purpose. Several issues related to soldering, such as dissolution, intermetallicformation and microstructure of solder joints, will also be discussed in terms of diffusional processes.
