Scope The symposium covers research advances in electronic interconnecting materials and their technologies, with special emphasis on Pb-free solders and new materials and structures for next-generation interconnects. Advances in microelectronic, optoelectronic and nanoelectronic device continue to require new materials and technologies to meet the increasing electrical, thermal, mechanical, reliability, performance and environmental demands placed on interconnects and packaging at all levels. In this symposium, emerging interconnect and packaging technologies will be examined, as well as insights into existing materials and technologies, including Pb-free and RoHS-compliant materials and processes will be discussed.

Topics include, but are not limited to:

- Interconnect materials, manufacturing and reliability from chip assembly to printed wiring board level interconnection
- Pb-free solder reliability, including tin whiskers, tin whisker mitigation, thermal aging, thermomechanical reliabilities, mechanical fatigue, drop performance, and electromigration
- Interconnects for emerging technologies, including 3-D packaging technologies, through silicon vias (TSVs), wafer level package (WLP), interconnects on flexible electronic modules and nano-materials technology
- Developments in high temperature Pb-free solders and associated interconnects for automotive and power electronics
- Fundamental materials behavior including phase transformations, solidification, microstructure evolution, corrosion, mechanical, thermal and electrical properties
- Continuing challenges in implementing Pb-free solders and RoHS-compliant materials including materials compatibility, including wetting; phase transformations; void formation and growth
