Top Chipmakers Samsung and TSMC embrace ASML's $400M machines, agree to major chipmaking change

Leading chipmakers Samsung Electronics and Taiwan Semiconductor Manufacturing Co. (TSMC) have announced plans to adopt ASML's latest chipmaking machines over the next several years. They also joined Intel in agreeing to a crucial technology change that could boost chip production on the new machines by 40 percent.

This signifies the semiconductor industry's broader embrace of high NA EUV photolithography technology, which can cost up to $400 million per machine and is only provided by the Dutch technology company ASML, Bloomberg reports. The technology would allow chip designers to implement even smaller features in potentially more powerful and efficient next-generation chips produced for AI data centers and consumer electronics such as smartphones, tablets, and laptops.

ASML's EUV (extreme ultraviolet) lithography machines enable chipmakers to use powerful laser light to imprint patterns in silicon wafers, layer by layer, and gradually form the computer circuitry that makes silicon chips work. Improving such EUV technology has required finding more powerful sources of light with even shorter wavelengths capable of creating even smaller features on silicon wafers.

Why This Matters

The adoption of ASML's $400M high NA EUV machines signals the next leap in semiconductor manufacturing, enabling smaller, more powerful chips critical for AI and consumer electronics.
The industry-wide agreement on large-format photomasks could increase chip production efficiency by 40 percent, potentially lowering costs and accelerating availability of advanced chips.
This move cements ASML's monopoly in advanced lithography, with implications for global chip supply chains and technological competition.

Background

The semiconductor industry has relied on EUV (extreme ultraviolet) lithography for years, using ASML's machines to etch increasingly tiny circuit patterns on silicon wafers. ASML is the sole supplier of EUV lithography systems, making it a linchpin in global chip production. The transition to high NA (numerical aperture) EUV represents a generational step forward, offering higher resolution to create smaller features. The key technology change involves shifting from traditional 6-inch photomasks to larger 12-inch (large-format) masks, which allow more complex patterns and greater throughput.

Key Perspectives

Samsung Electronics: As a leading memory chip and foundry player, Samsung aims to use high NA EUV to maintain competitiveness in advanced nodes for AI and mobile chips, benefiting from the production boost. TSMC: The world's largest contract chipmaker is committing to the new technology to serve customers like Apple and Nvidia, ensuring it can deliver next-generation processors. Intel: Already an early adopter, Intel's agreement with Samsung and TSMC signals industry consensus on the mask standard, reducing fragmentation and enabling faster ecosystem development. Critics/Skeptics: The high cost (up to $400M per machine) could limit adoption to only the largest chipmakers, potentially widening the gap between leaders and smaller foundries. Retooling fabs for new masks also poses significant operational challenges.
