ASML lines up key buyers for High‑NA EUV

Taiwan Semiconductor Manufacturing Co. (TSM) and Samsung Electronics have committed to deploy ASML’s High‑NA extreme ultraviolet lithography systems. These next‑generation tools are intended for the most advanced semiconductor manufacturing processes as chipmakers prepare for further growth in artificial intelligence and data‑center demand.

The commitments bring two of the world’s largest contract chip manufacturers into alignment around ASML’s latest EUV platform. Their plans signal that High‑NA technology is expected to play a central role in producing future generations of high‑performance processors.

High‑NA EUV tools are designed to pattern smaller features and support more complex chip designs than earlier systems. By adopting these machines, TSMC and Samsung are positioning their fabrication lines to handle more advanced and larger AI chips that require tight performance and power specifications.

The focus on AI and data‑center applications reflects current demand patterns in the semiconductor industry. As workloads grow more intensive, chipmakers are looking to lithography solutions that can support increased transistor density and sophisticated packaging for high‑end processors.

ASML has stated that it will add about 30% to its total EUV capacity in 2027. This expansion is intended to increase the number of EUV systems the company can produce, encompassing both existing and High‑NA platforms.

While ASML has provided this overall EUV capacity target, it has not given a recent forecast for the number of High‑NA machines it expects to sell. The absence of detailed volume guidance leaves the precise adoption pace unclear, even as leading customers have signaled strong interest.

Analysts have indicated that firm commitments from TSMC and Samsung give ASML greater visibility for planning future production capacity. With major customers aligning around High‑NA EUV, ASML gains more clarity on how to phase its manufacturing ramp and resource allocation.

The combination of confirmed customer plans and a defined EUV capacity expansion in 2027 underscores the strategic importance of High‑NA tools. These developments place ASML at the center of the transition to more advanced lithography required for next‑generation AI and data‑center chips.
