ASML Readies Next-Gen EUV Tools for Mass Production
ASML announced that its next-generation Extreme Ultraviolet (EUV) lithography tools are now ready for mass production. The development is a key milestone for the semiconductor industry, enabling chipmakers to scale advanced-node manufacturing at volume. The new tools are considered critical for producing the next wave of AI accelerators and other leading-edge silicon.
The new "High-NA" EUV systems, officially the Twinscan EXE:5000 series, represent the next step in shrinking the features on a chip. They can print transistors 1.7 times smaller and achieve transistor densities 2.9 times higher than the previous generation of EUV tools. This leap is enabled by a change in the system's optics, increasing the numerical aperture from 0.33 to 0.55, which allows for an 8nm resolution. Each of these next-generation machines carries a price tag of approximately $380 million to $400 million, more than double the cost of their predecessors. The first system was shipped to Intel in December 2023, and its installation required 250 crates and 250 engineers over six months. Other early adopters expected to receive these systems include Samsung, TSMC, and SK Hynix. This technology is considered essential for manufacturing chips at the 2nm node and below, which are critical for future AI and high-performance computing applications. By enabling finer circuit patterns in a single pass, High-NA EUV simplifies the manufacturing process, reducing the need for complex and costly multi-patterning techniques. This simplification can lead to faster production times and higher yields. Intel is aggressively adopting the new technology for its upcoming 14A process node. In contrast, TSMC is taking a more cautious approach, planning to continue using existing EUV tools for its A14 node and potentially delaying High-NA adoption due to the high cost and its ability to extend current technology. Samsung is reportedly receiving its first High-NA tool and may use it for its 2nm process. The readiness for mass production was demonstrated after the tools successfully processed 500,000 silicon wafers with limited downtime. Despite this milestone, chipmakers will likely need two to three years of testing and development before fully integrating the new machines into their high-volume production lines. ASML plans to be able to manufacture 20 High-NA systems annually by 2028 to meet anticipated demand.
