Predicting the reliability of zero-level TSVs

Abstract

The ability to predict TSV reliability still in its infancy and is hampered by little published test data (primarily simulation). Any prediction must take into account changes in interfacial material. DfR recommends an approach of: don't simulate/test nominal; investigate realistic worst-case. However, there is no need to reinvent the wheel. A significant amount of relevant material, especially in regards to interfacial reliability can be found in studies on fiber-reinforced ceramic composites.
