Redesigning high-NA EUV A researcher from the Okinawa Institute of Science and Technology (OIST) proposes redesigning the illumination systems and projectors used in high-NA EUV lithography to reduce optical effects and enhance resolution. In the proposed projector design, the collector mirrors in the illumination system have a simpler design to bring short wavelengths of light from the EUV... » read more

Building A Production-Ready Optically Connected Rack For AI Scale-Up


By Nandita Aggarwal and Nicholas Chang As AI models drive compute demand, servers keep getting bigger. Rack‑scale AI systems (such as the 72-GPU systems from NVIDIA or AMD) enable many GPUs to work together through system-level optimization. They push beyond the limits of single-chip performance and meet the soaring compute needs of the AI era. But this is just the beginning. The next s... » read more

Energy-Efficient Liquid Cooling for Advanced Semiconductor Packaging (KAIST)


A new technical paper, "Highly energy-efficient manifold microchannel for cooling electronics with a coefficient of performance over 100,000," was published by researchers at KAIST. The study presents a CMOS-compatible manifold microchannel cooler that removes over 2,000 W/cm² using single-phase water at only 8 kPa pressure drop, achieving a record COP of 106,000—a significant improvement... » read more

Engineer’s Guide to Simulating Electronics Cooling: eBook


Struggling with overheating PCBs, airflow bottlenecks, or long thermal simulation runtimes? As power densities rise and form factors shrink, electronics cooling is no longer a late-stage check — it’s a core design requirement. Poor thermal performance leads to hotspots, reduced reliability, field failures, and costly redesigns. Learn how to use intelligent thermal simulation to predic... » read more

Liquid Cooling Drives Other Localized Cooling


Key Takeaways: When converting from air to liquid cooling, components without liquid may become too hot. An entire board or system must undergo thermal analysis to ensure that any components that were once cool enough remain cool. Alternative cooling techniques may be needed for components without liquid cooling. Liquid cooling is proving effective at cooling high-power chip... » read more

Liquid Cooling Gains Traction In Data Centers


All electronics generate heat, and that heat must be removed to ensure those electronics don’t overheat. Moving air has been the predominant approach for decades, with liquid cooling limited to particularly intense computing workloads, largely in the supercomputing domain. With the rise in AI, data-center power density has grown to the point where liquid cooling is now seeing a larger buil... » read more
