Identifying Sources Of Silent Data Corruption


Silent data errors are raising concerns in large data centers, where they can propagate through systems and wreak havoc on long-duration programs like AI training runs. SDEs, also called silent data corruption, are technically rare. But with many thousands of servers, which contain millions of processors running at high utilization rates, these damaging events become common in large fleets. ... » read more

IoT Security By Design


After years of anticipation and steady uptake, the Internet of Things (IoT) seems poised to cross over into mainstream business use. The percentage of businesses utilizing IoT technologies has risen from 13% in 2014 to approximately 25% today. Global projections indicate that the number of IoT-connected devices is expected to reach 43 billion by 2030, nearly tripling from the figures in 2018. O... » read more

Coaxial Test Sockets Are In The Critical Path Of Advanced AI/CPU Products


Advanced AI/CPU processors demand extreme high frequency and power performance from SLT and ATE test sockets. These sockets are in the critical path at the end of a very costly silicon fabrication and advanced packaging manufacturing process. Yield loss at this point in the process is catastrophic to the bottom line. We at Modus Test, working in conjunction with our customers, have seen first-h... » read more

E-Beam Inspection Proves Essential For Advanced Nodes


Electron-beam inspection is proving to be indispensable for finding critical defects at sub-5nm dimensions. The challenge now is how to speed up the process to make it economically palatable to fabs. E-beam inspection's notorious sensitivity-throughput tradeoff has made comprehensive defect coverage with e-beam at these advanced nodes especially problematic. For Intel’s 18A logic node (~1.... » read more

Chip Complexity Drives Innovation In Automated Test Equipment


Innovations in semiconductor technology—such as advancements in AI high-performance computing (HPC), Angstrom-scale silicon process nodes, silicon photonics, and automotive xEV wideband gap power transistor applications—require automated test equipment (ATE) to evolve at an unprecedented rate. As chip complexity grows, the challenges in design, manufacturing, and test multiply. It is a comp... » read more

Atomic Force Microscopy: The Definitive AFM Modes Handbook


This handbook illustrates the wide variety of operating modes available on Bruker AFMs, going well beyond the standard high‑resolution topographic imaging capabilities of AFM. The modes are broken into seven separate categories: morphology, electromagnetic properties, thermal properties, mechanical properties, chemical properties, electrochemical properties, and manipulation. Each category be... » read more

Need For Speed Drives Targeted Testing


As packaging complexity increases and nodes shrink, defect detection becomes significantly more difficult. Engineers must contend with subtle variations introduced during fabrication and assembly without sacrificing throughput. New material stacks degrade signal-to-noise ratios, which makes metrology more difficult. At the same time, inspection systems face a more nuanced challenge — how t... » read more
