Intel has revealed that its flagship products based on Intel 18A process technology, Panther Lake (an AI PC client processor) and Clearwater Forest (a server processor), have successfully powered on and booted operating systems. This occurred less than two quarters after tape-out, with manufacturing set to commence in 2025. Also, the first external client is expected to tape out on Intel 18A in the first part of next year.
This introduction of the two products distinguish Intel Foundry as the first to offer RibbonFET gate-all-around transistors and PowerVia backside power technology to its clients. RibbonFET and PowerVia are accessible to all customers via ecosystem EDA and IP tools and process flows.
RibbonFET technology provides enhanced control over the electrical current in the transistor channel, allowing for chip miniaturisation and decreasing power leakage. PowerVia removes power delivery from the front side of the wafer, enhancing signal routing, lowering resistance and increasing power efficiency. These technologies are intended to improve computational performance and battery life in future electronic gadgets.
Panther Lake and Clearwater Forest booted operating systems without any further setups or adjustments. Panther Lake has also exhibited DDR memory performance at the desired frequency, demonstrating that the technology is ready. Clearwater Forest, which is set to be introduced next year, will integrate RibbonFET, PowerVia and Foveros Direct 3D technologies to increase density and improve power handling.
Intel's foundry business’ EDA and IP partners received access to the Intel 18A PDK 1.0 last month. These partners are currently improving their tools and design routines to help external foundry customers design Intel 18A chips.
RibbonFET and PowerVia for Intel 18A represent a significant step forward in process technology, giving foundry customers capabilities to accelerate AI computing and other high-performance applications.
