Precision Under Pressure: Managing Materials Complexity In Advanced Packaging


In the race to extend Moore's Law through advanced packaging, the limits of precision are no longer defined solely by lithography. Increasingly, they are dictated by the unpredictable behavior of materials. Semiconductor packaging today is no longer limited to just silicon and copper. It includes an expanding range of polymers, adhesives, dielectrics, exotic metals, along with substrates suc... » read more

Scaling Memory With Molybdenum


Molybdenum is looking increasingly promising as a replacement for a variety of metals commonly used in semiconductor manufacturing today, especially at leading-edge nodes. One by one, chipmakers are crossing metals off the list at advanced nodes. While ruthenium liners are nearly ready for production, the metal is not ready to replace copper in highly scaled interconnects. Ruthenium is very ... » read more

Virtual Twins: Layers Of Challenges


Virtual twins can provide deep insights into complex systems at any point in time, but creating them requires integrating a stack of abstractions that don't naturally go together. One abstraction may be mechanical, another electrical, and the data used to create those abstraction layers needs to be fused together logically and updated over time. David Fried, corporate vice president at Lam Rese... » read more

Chip Industry Week in Review


The U.S. is considering annual approvals for Samsung and SK hynix to export chipmaking tools and materials to their factories in China, replacing perpetual waivers granted under the validated end user system, reports Bloomberg. The proposal, presented by the U.S. Commerce Department to South Korean officials, would require the companies to reapply each year for specific quantities of restricted... » read more

Chip Industry Week in Review


Cadence plans to buy Hexagon AB's design and engineering business to accelerate expansion in physical AI and system design and analysis. Cadence will pay ~US$3.1 billion in cash and issue stock, with the deal expected to close in early 2026. PWC issued a 104-page in-depth analysis of semiconductor technology and markets, highlighting a broad swath of changes: $1T in annual revenue by 2030, ... » read more

How Semiconductor Fabs Use Water


Water — lots of it — is a critical enabler for advanced chip architectures, lithography, and back-end packaging. It feeds the ultra-pure water loops that touch every wafer, sluicing heat out of tools that run hotter at each node, and carrying spent chemistries to treatment. The natural reaction to reports that fabs “use millions of gallons of water” is concern, but the engineering re... » read more

Why 3D NAND Layers Bend (And How To Prevent It)


3D NAND flash memory is built by vertically stacking multiple alternating layers (tiers) of silicon nitride (SiN) and oxide (TEOS) on top of each other. A major challenge in producing multilayered 3D NAND devices is tier bending and tier collapse. These undesirable conditions can be caused by a combination of factors. Using the virtual Design of Experiment (DOE) capabilities in SEMulator... » read more

Manufacturing At The Limits


Hybrid bonding has been in production for several years, with mature flows capable of delivering robust yields using 10µm interconnects. At that scale, processes can tolerate hundreds of nanometers of overlay variation, modest differences in wafer bow, and particle sizes rivaling the interconnect height without catastrophic impact. Hybrid bonding is compatible with optical metrology, existing ... » read more

Blog Review: Aug. 6


Cadence's Shyam Sharma checks out key features of the LPDDR6 specification, including data transfer speeds that can reach up to 14.4Gbps, two sub-channels per device, metadata built into the data packets, and row hammer mitigation. Synopsys' Frank Malloy and Vincent van der Leest describe the essential role that a hardware root of trust plays in providing a secure foundation for all other se... » read more
