Managing The Huge Power Demands Of AI Everywhere


Before generative AI burst onto the scene, no one predicted how much energy would be needed to power AI systems. Those numbers are just starting to come into focus, and so is the urgency about how to sustain it all. AI power demand is expected to surge 550% by 2026, from 8 TWh in 2024 to 52 TWh, before rising another 1,150% to 652 TWh by 2030. Commensurately, U.S. power grid planners have do... » read more

Advanced Packaging Drives Test And Metrology Innovations


Advanced packaging has become a focal point for innovation as the semiconductor industry continues to push for increased transistor density and better performance. But the pace of change is accelerating, making it harder for the entire ecosystem to keep up with those changes. In the past, major developments were roughly on an 18-month to 2-year cadence. Today, this is happening every few mon... » read more

Batteries Look Beyond Lithium


Lithium batteries dominate today’s rechargeable battery market, and while they have been wildly successful, challenges with lithium have spurred research into alternative chemistries that can improve on some of lithium’s downsides and still keep as many of the upsides as possible. So far, none of the alternative batteries has seen commercial success, but several variants have moved beyon... » read more
