ASML Set to Unveil High-NA EUV Tool

ASML, a leading manufacturer of lithography machines, has announced that it will deliver the industry’s first High-NA extreme ultraviolet (EUV) lithography scanner by the end of this year. The machine, called the Twinscan EXE:5000 pilot scanner, with a 0.55 numerical aperture (NA), is being developed to help chipmakers learn how to effectively utilize High-NA EUV technology. This development is seen as a significant step forward in the advancement of EUV lithography machines.

The current most advanced EUV scanners in use are ASML’s Twinscan NXE:3400C and NXE:3400D, which have a 0.33 NA and can achieve a resolution of 13 nm. While this resolution is suitable for manufacturing technologies with metal pitches between 30 nm and 38 nm, it falls short when pitches drop below 30 nm. To address this issue, the industry is working on High-NA EUV scanners with a 0.55 NA, which can achieve an 8 nm resolution for manufacturing technologies planned for the latter half of this decade.

However, the development of High-NA scanners has faced some challenges. ASML CEO Peter Wennink acknowledged that a few suppliers encountered difficulties in ramping up production and meeting the required technological quality, resulting in some delays. Despite these challenges, ASML remains on track to ship the first High-NA scanner this year.

The introduction of High-NA scanners will not only require new optics but also necessitate a larger light source and new fab structures, leading to significant investments. Reports suggest that each High-NA scanner could cost between $300 million and $400 million, compared to over $200 million for the current 0.33 NA EUV scanners.

Intel initially planned to use ASML’s High-NA tools for its 18A (1.8 nm) production node, scheduled for high-volume manufacturing in 2025. However, Intel has since accelerated its 18A production to the latter half of 2024 and opted to use ASML’s Twinscan NXE:3600D/3800E with two exposures, as well as Applied Material’s Endura Sculpta pattern-shaping system to reduce the need for EUV double patterning.

Intel is expected to be the first customer to receive ASML’s pilot High-NA scanner. The company’s developers and engineers will use the machine to adjust Intel’s process technologies for future production tools. It remains unclear how and when Intel will integrate these tools into their processes, but considering the long-term nature of the 18A node, there is a possibility that High-NA EUV will still be utilized.

Samsung Foundry and TSMC are also planning to start chip production on their 2 nm-class nodes (SF2, N2) in late 2025. However, their plans regarding High-NA machines are still uncertain.

The development of ASML’s High-NA EUV lithography scanner marks a significant milestone in the industry’s pursuit of more advanced chip manufacturing technologies. While challenges remain, this technology has the potential to revolutionize the semiconductor industry and enable the production of smaller, more powerful chips.
