TSMC and Samsung Join Intel in Adopting ASML's $400 Million High-NA EUV Machines

The global semiconductor industry has reached a pivotal agreement to standardize next-generation lithography tools and photomask sizes. TSMC and Samsung have committed to adopting ASML's High-NA Extreme Ultraviolet (EUV) lithography machines, joining Intel in a coordinated effort to scale the production of advanced AI accelerators and memory chips.

Each High-NA EUV system carries a price tag of approximately $400 million. Despite the steep cost, the industry is moving toward a critical technical transition: shifting from the decades-old 6-inch photomask standard to 12-inch masks. This change is expected to increase the throughput of High-NA machines by as much as 40%, significantly reducing the cost per chip and increasing overall productivity.

The Path to Adoption

Lithography is the fundamental process of using light to etch intricate patterns into silicon wafers, and ASML remains the sole global provider of EUV equipment. While Intel has already integrated High-NA machines into its workflow, TSMC had previously remained cautious, weighing the massive capital expenditure against the actual productivity gains.

Implementation timelines now vary by manufacturer. Samsung plans to deploy High-NA EUV for the production of memory chips by 2028. TSMC is scheduled to adopt High-NA systems starting in 2030. While the industry has agreed to the 12-inch mask transition, TSMC's specific timeline for full-scale production remains fluid, though a pilot line for the larger masks is mentioned for 2031.

Why the Shift Matters

This transition is essential for the continued evolution of AI hardware. By increasing throughput and simplifying the design process, these tools allow manufacturers to produce smaller, more powerful transistors more efficiently. This scalability is critical for the expansion of high-performance computing and the massive data centers that power modern artificial intelligence.

Marco Pieters, CTO at ASML, described the shift as a "huge opportunity" that represents a "significant step in productivity." For the manufacturers, the move is about survival in a high-demand market. TSMC CEO C.C. Wei noted that the company believes in the "power of collaboration to overcome technical barriers before they become economic barriers for the semiconductor industry.

What's Next

As the industry moves toward the 2028 and 2030 deadlines, the focus will shift to the successful execution of the 12-inch photomask transition. The ability of these companies to synchronize their hardware updates will determine how quickly the next generation of AI chips can reach the market. While the current focus is on High-NA, the industry continues to monitor the long-term roadmap for even smaller transistor features and the potential for further lithography breakthroughs.
