This article examines hybrid bonding inspection challenges, identifying defect sources and evaluating nondestructive techniques, suggesting AI-driven solutions for improvement.

Key Points

This article explores the inspection and metrology challenges associated with hybrid bonding in 3D interconnects.
Examined surface planarization, activation, alignment, and thermal bonding stages.
Cataloged defect sources such as planarity variations and misalignments.
Evaluated established nondestructive techniques like acoustic microscopy and X-ray computed tomography.
Current techniques struggle to provide nanoscale resolution and manufacturing-compatible throughput.
No single method effectively delivers full-field coverage and subsurface visibility.
Emerging solutions include AI-driven classification and multi-modal inspection frameworks.
