Indium Corporation Expert to Present on Interconnect Reliability at IEEE Symposium
October 21, 2022
Indium Corporation’s Strategic Advisor Dr. Dongkai Shangguan will deliver a keynote presentation on interconnect reliability at the IEEE Symposium on Reliability for Electronics and Photonics Packaging (IEEE REPP) in a hybrid event on Nov. 9-10, Santa Clara, Calif., US., and online.
Interconnect reliability is critical to the reliability of semiconductor packaging and electronic systems. As newer forms of interconnects emerge to meet the demand for high density and high performance, interconnect reliability is becoming more complex and more critical.
The growing adoption of heterogeneous integration leads to increased diversity of interconnects (with different geometries, materials, and interfaces) in the same package, with complex (and often interactive) reliability failure modes and mechanisms. Finer pitch interconnects in advanced packaging are more susceptible to failures due to electromigration, interfacial reactions, etc. Cu direct bonding, without solder, presents new considerations in interconnect reliability.
At the same time, as electronic products become more pervasive in application, interconnect reliability must be considered holistically with regard to environmental conditions, from mechanical and thermomechanical to electrical and electrochemical. These considerations will impact reliability engineering for semiconductor devices, from design for reliability to accelerated testing and analysis. Yet another important dimension for interconnect reliability involves sustainability of electronic products, which demands environmentally friendly materials and processes, such as no-clean soldering, lead-free soldering, low-temperature soldering, etc.
Understanding of the failure mechanisms for different interconnect materials is of great importance to interconnect reliability and, ultimately, reliability of semiconductor devices and electronic systems.
