Summary: As always, manufacturing and performance take the forefront in regards to semiconductor packaging. The introduction of copper pillars has helped increase the number of I/Os and current density. The increasing use of ELK and ULK, especially at higher metal layers, has allowed for lower RC constants and better performance. However, both of these changes can come at a cost. A number of companies are reporting challenges with these new structures, especially at 28nm and 16nm process nodes. This presentation will review the current status of copper pillar and ELK, the potential risks both introduce into assembly and long-term reliability, and avenues to evaluate and mitigate any life-limiting mechanisms.
