ASML High NA EUV Machines | Why TSMC and Samsung Are Investing

Industry Leaders Adopt High NA Lithography

TSMC and Samsung have officially committed to using ASML’s newest High NA extreme ultraviolet (EUV) lithography machines. This decision marks a significant shift in semiconductor manufacturing as chipmakers race to meet the extreme performance demands of modern artificial intelligence hardware. Each machine carries a price tag of roughly $400 million, making the investment a massive capital expenditure for any manufacturer.

Samsung plans to begin using these tools in 2028 to produce DRAM memory chips. The company stated that this transition will extend their DRAM scaling roadmap while increasing overall manufacturing efficiency. TSMC intends to integrate the technology into its production cycle by 2030, citing the need for complex transistor architectures that current methods struggle to support. Both companies now join Intel in adopting this specialized equipment to push the limits of silicon pattern printing.

Technical Demands of Next Generation Chips

ASML’s High NA machines perform the critical task of printing microscopic circuit patterns onto silicon wafers. The new equipment allows for smaller and more intricate designs than previous generations, which is vital for the processing speeds required by current AI models. The technology essentially allows manufacturers to pack more computing power into a single chip.

Beyond the machines themselves, TSMC and Samsung have partnered with ASML to upgrade industry standards for 12-inch photomasks. These masks act as the stencils for printing circuits. Moving away from the current 6-inch format to a larger size should improve overall factory productivity. This transition is expected to lower production costs as manufacturing volumes for advanced chips increase globally.

Market Impact and Future Outlook

Investors are watching these adoptions closely as indicators of ASML’s long-term growth potential. The stock has seen a 120% increase over the past 12 months, and the commitment from major industry players provides more clarity on the future of the technology. Analysts at Barclays noted that the announcements serve as a positive signal for the broader chip manufacturing market.

While ASML has not released specific sales forecasts for the new units, the company previously announced plans to increase total EUV capacity by 30% in 2027. Demand remains strong, and the company faces a decision regarding further capacity expansion. The adoption of High NA tools represents a fundamental change in how the most advanced chips are built. As the industry moves toward 2030, the ability to produce these chips reliably at scale will determine market leadership among the world's largest foundries.
