Advancing Heterogeneous Integration Through Industry Roadmap Improvements


Heterogeneous integration requires comprehensive roadmaps to support collaboration across the design and manufacturing of the next generation of semiconductor products and the systems they support. A global team of researchers from a broad spectrum of industry, academia, and research institutes led by Intel has published a perspective in the March 2026 issue of Nature Reviews Electrical Enginee... » read more

Low-Temp Solders Are Suddenly Critical For Chiplets And Photonics


Key Takeaways: Tin-bismuth-based solders enable reduced warpage and compatibility with silicon photonics and other temperature-sensitive components. A novel soldering process using white light could help prevent cracks in flip-chip BGA package solder balls, while reducing the carbon footprint. Hypoeutectic Sn-Bi based solders prove especially promising as an SAC305 replacement. ... » read more

AI & Energy: Bending The Curve


By Pushkar P. Apte and Melissa Grupen-Shemansky Artificial intelligence (AI) is scaling at a pace that is reshaping semiconductor roadmaps, data center design, and long-term infrastructure strategy. AI promises many economic and social benefits, but the growth comes with an escalating demand for power, and energy has emerged as a major challenge. The AI & energy challenge AI training c... » read more

Enabling Production-Ready AI For Semiconductor Manufacturing


Semiconductor inspection has always been a scalability problem. Inspection teams are buried in manual reviews because the machines on the line throw false rejects, miss real defects, and can't learn from the data they're already producing. The job hasn't really changed in decades. Find defects faster. Find them with higher sensitivity. Keep cost down. And whatever you do, don't bury the review ... » read more

Cost-Effective High-Performance Flip Chip MicroLeadFrame (fcMLF) Package Introduction


Abstract "The demand for cost-effective leadframe packages continues to grow, particularly for automotive and commercial applications. These designs require smaller form factors, enhanced thermal and electrical performance, and proven reliability. Flip chip on leadframe technology offers significant advantages over traditional wire-bonded MicroLeadFrame (MLF) and high-cost laminate Flip Chip... » read more

Mask Technology Faces A New Set Of Challenges


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

Four-Tier Memory Hierarchy for LLM Reasoning (USC, UW)


A new technical paper, "Not All Thoughts Need HBM: Semantics-Aware Memory Hierarchy for LLM Reasoning," was published by researchers at USC and University of Wisconsin-Madison. Abstract "Reasoning LLMs produce thousands of chain-of-thought tokens whose KV cache must reside in scarce GPU HBM. The dominant response -- permanently evicting low-importance tokens -- is catastrophic for reasoni... » read more

Options Grow For Standardizing Data Movement And Sharing Resources


Semiconductor Engineering sat down to discuss memory interfaces, interconnects, and memory access scaling with Madhumita Sanyal, senior director of technical product management at Synopsys; Swadesh Choudhary, senior principal engineer at Intel; Siamak Tavallaei, senior principal engineer at Samsung SSI; and Mohsen Asad, senior director of technology at Credo. What follows are excerpts of a disc... » read more

Blog Review: May 20


Cadence's Siddh Virani demonstrates how to import and integrate foreign language logic into PSS on both Target and Solve platforms, opening possibilities for code reuse and cross-language collaboration. Synopsys' Sumit Vishwakarma finds that AI model training and inference workloads are forcing the industry to rethink not only how much compute fits in a rack, but how servers are architected ... » read more

Research Bits: May 19


Programmable PIC Researchers from the University of Washington designed a low-power programmable photonic integrated circuit that is electrically reconfigurable and can be mass-produced. “This optical chip could help to accelerate the prototyping cycle while reducing power consumption for applications like AI computing. Our study is also the first time someone has shown that these kinds o... » read more
