Can Fine-Pitch Hybrid Bonding Go High Volume?

By Gregory Haley - 16 Jul, 2026 - Comments: 0

Key Takeaways: Fine-pitch hybrid bonding extends a proven production technology into a manufacturing regime with much smaller margins for particles, surface variation, distortion, and placement error. Die-to-wafer integration allows known-good-die selection, but it exchanges wafer-level parallelism for repeated handling, alignment, and bonding operations. Reaching high volume will de... » read more

When The Test Cell Lies

By Gregory Haley - 07 Jul, 2026 - Comments: 0

Key Takeaways: A marginal test result can be electrically valid and still diagnostically misleading because the socket, load board, and thermal loop are now part of the measurement. Separating device drift from test-cell drift depends on tracking margins, variance, and calibration trends rather than bins alone. In advanced packages, a false pass destroys value downstream, a false f... » read more

Mask Economics Shape High-NA EUV Adoption

By Gregory Haley - 22 Jun, 2026 - Comments: 1

Key Takeaways: Mask costs are not stopping leading-edge scaling, but they increasingly influence design, node, and process choices. High-NA EUV will tighten requirements for CD, EPE, local CDU, mask 3D modeling, stitching, and materials. Reduced depth of focus in High-NA EUV will drive new resist, etch, film, and absorber approaches. Experts at the table: Semiconductor Engin... » read more

Making On-Chip Photonics Manufacturable

By Gregory Haley - 18 Jun, 2026 - Comments: 0

Key Takeaways: System-level energy and bandwidth pressures are pulling optics into the package faster than the manufacturing flow can mature. Photonics combines front-end fabrication, materials, thermal, cleanliness, and test into one problem that can’t be solved domain by domain. Test is moving upstream because discovering an optical failure after final assembly forfeits every goo... » read more

Why Analog And Mixed-Signal Chips Resist Adaptive Test

By Gregory Haley - 09 Jun, 2026 - Comments: 0

Key Takeaways Analog and mixed-signal test remains heavily specification-based because the measurements do not always produce a single expected result. The absence of objective coverage metrics has historically encouraged conservative test flows, which IEEE 2427-2025 begins to address. Separating device behavior from test-path variation is a prerequisite for any adaptive flow—and h... » read more

Curvilinear Masks Push The Limits Of Inspection And Metrology

By Gregory Haley - 27 May, 2026 - Comments: 0

Key Takeaways: Curvilinear masks require native data flows across design, mask data prep, writing, inspection, and metrology. Inspection is shifting from finding all defects to identifying which mask variations actually print on wafer. High-NA EUV will intensify inspection challenges, particularly for small printable defects and actinic contrast limits. Experts at the table... » read more

Mask Technology Faces A New Set Of Challenges

By Gregory Haley - 21 May, 2026 - Comments: 0

Key Takeaways: Mask inspection and repair remain the critical bottleneck, even as multi-beam writers have reduced mask-writing constraints. Curvilinear masks are becoming viable for critical layers, but qualification, metrology, and inspection standards still lag production needs. Scaling curvilinear requires curvilinear-native data flows, model-based checks, GPU/HPC compute, and les... » read more

Smart Test Collides With The Data Chain

By Gregory Haley - 12 May, 2026 - Comments: 0

Key Takeaways: The promise of smart test is a data-chain problem before it is an algorithm problem. A device can pass every checkpoint and still carry a latent defect the test record never captured. As test grows more adaptive, the validity of the measurement environment matters as much as the measurement itself. For years, the test roadmap has pointed toward more adaptive f... » read more

When Semiconductor Materials Misbehave

By Gregory Haley - 27 Apr, 2026 - Comments: 0

Key Takeaways Material behavior in production depends on the process context that no development environment can fully replicate. In advanced packaging, the interactions that cross domain boundaries are increasingly where failures originate. The most accurate materials data is also the most commercially sensitive, leaving simulation models calibrated against generic inputs rather tha... » read more

Panel-Level Packaging’s Second Wave Meets Engineering Reality

By Gregory Haley - 16 Apr, 2026 - Comments: 0

Key Takeaways Panel-level packaging is arriving not because the engineering is ready, but because wafer-level economics are breaking down. Glass improves the warpage and dimensional stability problems of organic substrates but introduces a different class of failure modes that require materials solutions, not process adjustments. The central challenges of panel-level processing are m... » read more
