Intel has completed development of the Intel 18A (1.8nm class) and Intel 20A (2nm class) manufacturing processes used to manufacture its own products, and has also developed chips for customers in the Intel Foundry Services (IFS) division. , report UDN.
Wang Rui, president and chairman of Intel China, said at the event that the Intel 18A (18 Angstrom class) and Intel 20A (20 Angstrom class) manufacturing processes have been developed. This does not mean that the production nodes are ready for commercial production, but that Intel has determined all the specifications, materials, requirements and performance targets for both technologies.
Intel’s 20A fabrication technology relies on full-gate RibbonFET transistors and uses backside power delivery. Shrinking the metal pitch, introducing an entirely new transistor structure, and adding a rear power supply at the same time is a risky move, but 20A will allow Intel to leapfrog its competitors TSMC and Samsung Foundry. expected. Intel plans to start using this node in the first half of 2024.
Intel’s 18A manufacturing process further refines the company’s RibbonFET and PowerVia technologies to reduce transistor size. Development of this node is apparently going well, with Intel halting its introduction from his 2025 until the second half of his 2024. Intel originally planned to use ASML’s Twinscan EXE scanner with 0.55 numerical aperture (NA) optics at the 1.8 Angstrom node, but decided to use this technology sooner, Extensive use of existing Twinscan NXE scanners with NA 0.33 optics and EUV double patterning must be relied upon.
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 manufacturing technology is developed both for its own products as well as for the chips IFS manufactures for its foundry customers.
Intel CEO Pat Gelsinger said in a recent conference call with analysts: and investors. Additionally, Intel 18A development continues and he has already shared his release of engineering PDK 0.5 (Process Design Kit) with his main customers, with a final production release expected in the coming weeks. is. “
