Intel has completed development of its Intel 18A (1.8nm-class) and Intel 20A (2nm-class) fabrication processes that will be used to make the company's own products, as well as chips for clients of its Intel Foundry Services (IFS) division, reports UDN.  

Wang Rui, president and chairman of Intel China, said at an event that the company had finalized the development of its Intel 18A (18 angstroms-class) and Intel 20A (20 angstroms-class) fabrication processes. This does not mean that the production nodes are ready to be used for commercial manufacturing, but rather that Intel has determined all specifications, materials, requirements, and performance targets for both technologies. 

Intel's 20A fabrication technology will rely on gate-all-around RibbonFET transistors and will use backside power delivery. Shrinking metal pitches, introducing all-new transistor structure and adding backside power delivery at the same time is a risky move, but it is expected that 20A will allow Intel to leapfrog the company's competitors — TSMC and Samsung Foundry. Intel plans to start using this node in the first half of 2024. 

Intel's 18A manufacturing process will further refine the company's RibbonFET and PowerVia technologies, as well as shrink transistor sizes. Development of this node is apparently going so well that Intel pulled in its introduction from 2025 to the second half of 2024. Intel originally planned to use ASML's Twinscan EXE scanners with a 0.55 numerical aperture (NA) optics for its 1.8 angstroms node, but because it decided to start using the technology sooner, it will have to rely on extensive use of existing Twinscan NXE scanners with 0.33 NA optics, as well as EUV double patterning.  

The company itself expects its 1.8nm-class manufacturing technology to be the industry's most advanced node when it enters high-volume manufacturing (HVM) in the second half of 2024. 

Intel's 20A and 18A fabrication technologies are being developed both for the company's own products as well as for chips that will be produced by IFS for its foundry customers. 

"We have an active pipeline of engagements with seven out of the 10 largest foundry customers coupled with consistent pipeline growth to include 43 potential customers and ecosystem partner test chips," said Pat Gelsinger, chief executive of Intel, on a recent conference call with analysts and investors. "Additionally, we continue to make progress on Intel 18A, and have already shared the engineering release of PDK 0.5 (process design kit) with our lead customers and expect to have the final production release in the next few weeks."
