Co-Packaged Optics Testing Faces Steep Data Center Ramp


Key Takeaways: Device interface board must balance flexibility in handling with customization for different optical connectors. Test fixtures should account for DUT socketing challenges, such as warpage, coupling, and interference. Advanced data management practices will help speed yield learning. Integrating photonic and electrical ICs into co-packaged optics (CPO) requires... » read more

HBM4 Sticks With Microbumps, Postponing Hybrid Bonding


The next generation of high-bandwidth memory, HBM4, was widely expected to require hybrid bonding to unlock a 16-high memory stack. A JEDEC move made that unnecessary with this generation, but it’s merely a postponement, not a cancellation. HBM has been in high demand for AI in data centers — especially for training. Data movement dominates energy consumption, and high-bandwidth memories... » read more

Reliability And Traceability In Advanced Packages


The move from planar SoCs to advanced packages can improve performance and provide flexibility in large designs, which are difficult to fit onto a single reticle-sized die. But ensuring the device works as expected remains a challenge. There are multiple packaging options to choose from — 2.5D, fan-out wafer-level packaging, 3D-ICs, and various types of system-in-package — and many possible... » read more

What’s Next for 2.5D Packaging?


Interposers and bridges, two of the key elements for interconnecting multiple chips and chiplets in an advanced package, are undergoing fundamental changes in how they're built and assembled. Interposers are becoming thicker and more complex, while bridges are being used to reduce the assembled cost. Both efforts are facing new challenges. Interposers are effectively platforms on which mu... » read more

Adaptive Test Gaining Ground For HPC And AI Chips


Adaptive test is starting to gain traction for high-performance computing and AI chips as test programs that rely on static limits and fixed test sequences reach their practical limits. The growing complexity of multi-die assemblies and power delivery, along with increased stresses, are forcing a shift toward real-time, data-driven optimization at the test cell. “It’s the same old pro... » read more

Zero-Trust Data Sharing Architectures Redefining Chip Manufacturing


Real-time security clearances are becoming increasingly common in the manufacturing of advanced-node semiconductors, where data sharing is both essential and a potential security threat. Data security is a well-known issue in semiconductor manufacturing, but much of it is based on an outdated approach. In its place, zero-trust architectures [1] are now a requirement for new equipment and ins... » read more
