Challenges Facing the Detection of Leakage Current in Integrated Circuit (IC) Devices

Electrical characterizations were needed to identify the root cause of leakage issues in IC devices. The methodology required was dependent on the failure mode obtained during testing and global or nano-scale isolations had to be implemented accordingly. As such, challenges encountered in sample preparation or due to detection methodology choices for every isolation technique have to be addressed in order to localize the defective sites.
