Intel Moves Directly To 18A Process Node, Ends 20A Plans With Arrow Lake Shifting To External Nodes

Intel has announced that it is ending its 20A production plan and shifting to 18A instead while Arrow Lake will use external nodes.

Intel 20A Ends As 18A Node Takes Over, Arrow Lake Shifted To External Foundries But Packaged At Intel Foundry

Press Release: Since releasing the Intel 18A Process Design Kit (PDK) 1.0 in July, we have seen positive responses across our ecosystem and are encouraged by what we’re seeing from Intel 18A in the fab. It’s powered on and booting on operating systems, healthy, and yielding well – and we remain on track for launch in 2025.

One of the benefits of our early success on Intel 18A is that it enables us to shift engineering resources from Intel 20A earlier than expected as we near completion of our five-nodes-in-four-years plan. With this decision, the Arrow Lake processor family will be built primarily using external partners and packaged by Intel Foundry.

The journey to Intel 18A has been built on the groundwork laid by Intel 20A.

It enabled us to explore and refine new techniques, materials and transistor architectures that are crucial for advancing Moore's Law. With Intel 20A, we successfully integrated both RibbonFET gate-all-around transistor architecture and PowerVia backside power delivery for the first time, and these learnings have directly informed the first commercial implementation of both technologies in Intel 18A. This points to the iterative nature of semiconductor innovation, and we’re excited to bring these advancements to all Intel Foundry customers.

Focusing resources on Intel 18A also helps us optimize our engineering investments. When we set out to build Intel 20A, we anticipated lessons learned on Intel 20A yield quality would be part of the bridge to Intel 18A. But with current Intel 18A defect density already at D0 <0.40, the economics are right for us to make the transition now.
