This new iNEMI project will look at voids in 1st level interconnect, focusing on flip chip packages. Small voids (micro voids) can occur in solder-based flip chip joints during the assembly process and are a potential concern for applications that involve high electrical and thermal flux across the flip chip. They can also impact electromigration in the joint, adversely affecting the reliability of the electrical interconnect.
The small dimension of the flip chip bond and the interference of substrate and die metallization make it challenging to accurately locate and measure the size of the voids or percentage of voiding with X-ray, which is the preferred method of inspection for voids. There are currently no guidelines or standards that define an acceptable percentage of voiding or how the percentage of voiding relates to the reliability of the assembly.
Project Focus
The 1st Interconnect Void Characterization project plans to study voids in flip chip interconnect to determine their location and volume. It will also seek to understand how voiding in 1st level interconnect affects product reliability and what level of voiding is acceptable while maintaining reliability requirements. Click here for additional project information.
