How could ASML's EUV lithography monopoly affect SK Hynix's production capacity?
SK Hynix's advanced memory production relies on ASML's monopolistic EUV technology As the sole global manufacturer of Extreme Ultraviolet (EUV) lithography systems, ASML holds a monopolistic position in the advanced chip manufacturing sector. SK Hynix, as a major memory semiconductor supplier, relies on this critical equipment to produce its advanced chips. This structural dependency means that any operational issues, delays, or changes in the supply of ASML's EUV machines could directly impact SK Hynix's ability to maintain or expand its advanced production capacity.

How it reaches SK Hynix
-
ASML is the sole supplier of extreme ultraviolet (EUV) lithography systems, which are required to manufacture leading-edge logic and memory chips. The company reported Q2 2026 revenue of $10.65 billion, representing a 21.3% year-over-year increase. Additionally, Intel Foundry and ASML confirmed that High Numerical Aperture (High NA) EUV lithography is being used in high-volume manufacturing for select layers of Intel Core Ultra Series 3 processors.

Why it matters
SK Hynix, like TSMC, Samsung, and Intel, is locked into long-term capital expenditure cycles driven by the relentless demand for AI servers and advanced memory. Its ability to compete in the high-performance computing market is directly tied to its access to and operational status of the most advanced manufacturing tools available.
The structural dependency on ASML is shared across the entire semiconductor industry. ASML's monopoly means that while the demand for advanced chips is high, the supply chain for the necessary manufacturing tools is highly concentrated. This concentration creates a powerful, defensive floor for ASML's valuation but also introduces a critical single point of failure for its major foundry and memory customers.
What we don't know yet
- What is the impact of geopolitical export controls on ASML's ability to service SK Hynix's global operations?
- How might increased costs or delays in ASML's EUV supply chain affect SK Hynix's future capacity expansion plans?
