ASML, the Dutch lithography giant, says it will increase its production capacity for low-NA EUV machines by 30% by 2027. The plan, announced without a specific timeline for individual milestones, signals the company's bet that chipmakers will keep buying its most advanced gear for years to come.
Why the capacity increase matters
Low-NA EUV machines are the workhorses of modern chip fabrication. They use extreme ultraviolet light to etch tiny circuits onto silicon wafers, a process essential for making the latest processors and memory chips. A 30% capacity jump means ASML expects to ship significantly more of these systems than it does today. The company hasn't said how many units that translates to, but the percentage gives a clear direction: more supply for a market that has been hungry for EUV tools.
Demand for advanced chips isn't slowing. From data centers to smartphones, manufacturers need ever-smaller transistors. EUV lithography is the only way to get there at scale. ASML's move suggests it sees that demand holding strong through the end of the decade.
What low-NA EUV means for chipmaking
Low-NA EUV refers to the current generation of ASML's lithography systems, with a numerical aperture of 0.33. These machines have been in production for several years and are used by companies like TSMC, Samsung, and Intel to make chips at 7nm and smaller nodes. The technology is mature but still being refined. By expanding capacity, ASML is ensuring that chipmakers can get enough machines to meet their production targets without bottlenecks.
The company also sells high-NA EUV systems, which offer even finer resolution. But those are newer and more expensive. Low-NA EUV remains the volume workhorse. The 30% increase is about that workhorse, not the high-end niche.
ASML's production timeline
ASML didn't provide a year-by-year breakdown of how it will reach the 2027 target. The company typically ramps up production gradually, adding factory space and supplier capacity. It has been investing in its Veldhoven headquarters and in a new facility in Taiwan. The 30% goal likely involves both internal expansion and supply chain improvements.
The company's customers have been vocal about needing more EUV tools. Some chipmakers have complained about long lead times. This plan addresses that, but it will take years to materialize. ASML's order book is already full for the next couple of years, so the extra capacity will mostly benefit orders placed after 2025.
The broader chip industry context
The chip industry is in the middle of a global expansion. Governments in the US, Europe, and Asia are pouring money into domestic fabrication plants. Those fabs will need EUV machines. ASML's capacity increase is a direct response to that wave of investment. Without enough EUV tools, new fabs can't produce the most advanced chips.
But building EUV machines is complex. Each one contains tens of thousands of parts and requires extreme precision. ASML has been working with suppliers to scale up. The 30% target is ambitious but not unprecedented. The company has doubled its EUV output in the past five years.
ASML hasn't said whether the 30% increase will be enough to meet all demand. Chipmakers may still face shortages. But the plan gives them a clearer picture of what's coming. The next step is execution. ASML will need to hit its production targets quarter after quarter. Investors and customers will be watching closely.
