Intel’s 18A manufacturing effort reached a wider commercial audience on January 5, 2026, when the company launched Core Ultra Series 3 processors at CES. Intel said the family would power more than 200 PC designs.
Previously known as Panther Lake, Series 3 is Intel’s first product family built on 18A. The company also described versions tested and certified for embedded and industrial uses, including robotics and automation, extending the launch beyond consumer computers.
The January event followed a manufacturing push Intel had outlined the previous October. The process was developed and qualified in Oregon, with production moving toward higher volumes at Fab 52 in Chandler, Arizona. Intel’s October plan called for an initial processor shipment before year-end and broad availability in January.
Three pieces of engineering connect those factories to the finished processor.
RibbonFET changes the transistor architecture—the tiny switches used to process information. Intel designed it to support further scaling and more efficient switching.
PowerVia moves power delivery to the back side of the chip. Separating that routing from front-side signal connections addresses the difficulty of supplying electricity to increasingly dense circuitry.
Panther Lake also combines multiple chiplets, or separate pieces of silicon, into one processor. Intel’s Foveros packaging technology supports their integration and stacking. A finished chip therefore depends on both fabrication and the connections between its constituent parts.
Intel’s launch demonstrated the commercial path for its own designs. Winning outside designers as manufacturing customers remains a separate business task: those companies must choose the process and bring their products into production on it.
