SK Hynix Places Record $8 Billion ASML EUV Order to Feed AI Memory Boom

The Deal: 30 EUV Scanners, Two Fabs, Two Years

SK Hynix committed 11.95 trillion won (approximately $7.97 billion) to purchase roughly 30 extreme ultraviolet lithography machines from ASML, the largest single EUV order ever publicly disclosed by an ASML customer. The agreement runs through December 2027 and represents 9.97% of SK Hynix's total assets as of year-end 2024.

The scanners will be deployed across SK Hynix's M15X fab in Cheongju, where a second cleanroom recently opened with equipment installation moved forward two months ahead of the original May schedule, and the new Yongin Semiconductor Cluster, where the first fab is targeted for completion in 2027. SK Hynix's M16 fab in Icheon already deployed High-NA EUV equipment for mass production in September 2025.

HBM4 and Advanced DRAM Drive the Spending

The order is driven by surging demand for AI memory. SK Hynix is currently producing HBM4 on its 1b-generation process and plans to transition to the 1c process for the HBM4E variant. The same 1c process will serve DDR5 and LPDDR6 production. For HBM4E's logic die, SK Hynix will use TSMC's 3nm technology.

Bernstein analyst David Dao estimates the order covers approximately 30 new EUV machines at a unit cost of 300–500 billion KRW each. The investment targets what SK Hynix describes as "rising demand for AI memory, including HBM, while also addressing growing needs for general-purpose DRAM."

What This Means for Etch and Deposition Equipment

Every EUV scanner SK Hynix installs requires a full complement of upstream and downstream process tools to function. Advanced DRAM at the 1c node demands dozens of plasma etch steps per wafer — reactive ion etch for gate patterning, high-aspect-ratio etch for capacitor structures, and atomic layer etch for critical dimension control. Each new cleanroom filled with EUV scanners needs a corresponding fleet of etch chambers from suppliers like Lam Research and Tokyo Electron.

Thin film deposition requirements are equally substantial. HBM4 stacks multiple DRAM dies using through-silicon vias (TSVs) and hybrid bonding, each requiring precise ALD layers for high-k dielectrics, CVD tungsten and barrier metals, and PVD seed layers for copper interconnects. The 1c-node transition increases the number of deposition steps per wafer, pushing demand for tools like Applied Materials' Endura PVD platform and Lam Research's ALTUS ALD systems.

PECVD tools are also critical. Passivation layers, interlayer dielectrics, and hard masks for EUV patterning all require plasma-enhanced chemical vapor deposition. As SK Hynix scales HBM4E production, each stacked die adds deposition cycles that compound across an 8-high or 12-high stack.

Ripple Effects Across the Equipment Supply Chain

The $8 billion EUV headline understates the total equipment spend. For every dollar spent on lithography, memory fabs typically spend $0.60–$0.80 on etch and deposition tools combined. That implies an additional $5–6 billion in etch and deposition equipment orders flowing to suppliers over the same two-year window, just from SK Hynix.

Component suppliers deeper in the chain — plasma source manufacturers, sputtering target producers, vacuum pump makers, gas delivery systems, and process monitoring instrumentation — stand to benefit as well. Lead times for specialty components like RF generators and mass flow controllers have already been tightening as TSMC's record $56 billion 2026 capex budget competes for the same supply base.

SK Hynix's accelerated timeline at the M15X fab, moving equipment installation forward by two months, signals that the company is willing to pay premiums to secure tool deliveries ahead of competitors. Samsung and Micron face similar pressure to lock in deposition and etch capacity for their own HBM and advanced DRAM roadmaps.

Broader Market Context: Etch Equipment Headed to $28 Billion

The SK Hynix order lands in a market already running hot. Verified Market Research reported on March 26 that the global semiconductor etch equipment market is projected to nearly double from $14.51 billion in 2024 to $28.26 billion by 2032, growing at an 8.7% CAGR. Key drivers include the transition to sub-3nm nodes, AI workload expansion, and government-backed fab construction programs across Asia-Pacific, North America, and Europe.

Applied Materials, Lam Research, and Tokyo Electron dominate the etch equipment market, with Plasma-Therm and SPTS Technologies serving specialized segments. On the deposition side, ASM International is building a $320 million ALD hub in Arizona, while the overall ALD equipment market has already surpassed $7.9 billion. Meanwhile, at SEMICON China 2026 (March 25–27), Chinese equipment maker Naura Technology unveiled its NMC612H ICP etcher, claiming high-aspect-ratio etch capabilities that could begin displacing imported tools in Chinese fabs.

For equipment suppliers and their component vendors, the message is clear: AI-driven memory demand is converting into concrete purchase orders, and the etch and deposition tool pipeline is filling fast.
