Powering AI: The Semiconductor Ecosystem at the Foundation of Data Centers - Semiconductor Industry Association | SIA

This article highlights the central role of semiconductor technology in driving artificial intelligence (AI), emphasizing its foundational role as the core hardware layer underpinning modern AI system... Read original →

The AI data center boom has elevated semiconductors from peripheral components to the core value driver—chips now account for 95% of a rack’s worth, signaling that hardware defines AI capability. Technologically, HBM and 3D packaging are critical bottlenecks; low-cost compound semiconductors like GaN dominate volume and cap system efficiency. Geopolitically, U.S. export controls on advanced AI chips force hyperscalers to reroute supply chains, making packaging capacity in Taiwan, China and Hong Kong, China high-risk nodes. In market strategy, NVIDIA leverages full-stack lock-in, while AMD, Intel, and Chinese firms pivot to chiplet architectures to bypass process-node constraints. Over the next 12–24 months, capital will shift decisively toward AI-native silicon, starving general-purpose compute. More profoundly, with semiconductors consuming over 50% of data center CapEx, foundries and cloud giants will forge oligopolistic alliances where compute equals manufacturing leverage.
