X-ray inspection systems for Semiconductor Industry: The Invisible Infrastructure Behind Chiplet Reliability, HBM Yield and Advanced Packaging Scale-Up
A semiconductor package now hides more value than many older chips used to expose on their surface. In a 2.5D AI accelerator, one substrate can carry a logic die, HBM stacks, micro-bumps, underfill layers, silicon interposers, redistribution layers and hundreds of thousands of hidden joints. A defect of even 5–20 microns in a solder bump, void, bridge or crack can decide whether a...
