Background Information

Five (5) bare dice lead solder bumps were submitted for under‐
bump crack analysis from the following group

Stats ChipPac, ASEKH, Amkor, SCC, & TSMC. Bump de‐processing is to be performed on all dice. Afterwards, optical andSEM inspection is to be performed on all 5 dice looking for passivation
cracks around the bump pads. Finally, a non‐deprocessed
die is to be picked from each group and cross sectioned looking
for passivation
cracks underneath thebump/UBM interface from each group.

Physical Analysis:

All 5 dice with lead solder bumps from each group were de‐processed. All bumps were removed from the pads. Opticaland SEM inspection was performed on all dice looking for passivation
cracks around the bump pads. One non‐deprocesseddie from each group was encapsulated and cross sectioned to a row of bumps.

Die Cross Sections:

SEM inspection was performed all along the row of bumps looking for passivation
cracks.
