Episode notes
Choke Point In Packaging Metrology
- Onto Innovation sits at a supply-chain choke point supplying metrology and inspection gear essential for advanced packaging and yield control.
- Their tools ensure wafers and packages are defect-free during ramp-ups like HBM and GPU integration, preventing costly yield loss.
Dragonfly Optical Metrology Explained
- The Dragonfly is Onto Innovation's flagship optical metrology system used to measure critical features across packaging stacks.
- It leverages optical techniques (UV, polarized, IR) to inspect HBM cubes and GPU-package interfaces during manufacturing.
Metrology Targets HBM And GPU Integration
- Metrology covers diverse optical modalities to catch packaging issues before shipment to customers like TSMC.
- The hosts illustrate using side-view diagrams of HBM cubes packaged with logic to show where measurements control yield.
