INEMI Interim Report: Interconnection Modeling and Simulation Results for Low-Temp Materials in First-Level Interconnect

Estimated reading time: 1 minute

One of the greatest challenges of integrating different types of silicon, memory, and other extended processing units (XPUs) in a single package is in attaching these various types of chips in a reliable way. Key modulators for reliability are the maximum temperature that the silicon chip experiences during assembly bonding processes, interaction with chip warpage, and solder joint reliability.

INEMI’s Low-Temperature Material Discovery and Characterization for First-Level Interconnect Project has conducted simulation studies of low-temperature solder materials, including SAC305, eutectic SnBi and SnBiCuNi, using solder package structures with solder sphere and Cu pillar interconnections.

The project team will share results from these studies, including bump collapse simulation, thermal mechanical simulation and electromigration simulation. We will also talk about future plans for the project.
