Lithography is the chipmaking step that prints a circuit pattern onto a wafer, and shorter light wavelengths allow finer lines to be drawnCITE:E1. Extreme ultraviolet (EUV) lithography uses light at a 13.5-nanometer wavelength, making it the shortest-wavelength lithography technology currently in mass productionCITE:E1. That shorter wavelength is what lets chipmakers pattern the tiny features required for the most advanced process nodesCITE:E1.
EUV light at 13.5 nanometers is absorbed by almost every material, which forces the entire system to run inside a vacuum using specialized mirror-based optics instead of conventional lensesCITE:E2. The light source itself is generated by firing a high-power laser at tin droplets to produce a plasma, a process with extreme physics and engineering demands across the whole systemCITE:E2.
ASML, based in the Netherlands, is the only manufacturer in the world capable of mass-producing EUV lithography machines, with each unit priced in the hundreds of millions of dollarsCITE:E3. Advanced process nodes such as 2-nanometer and 3-nanometer chips cannot be manufactured without EUV, which makes ASML the single most critical point in the entire semiconductor supply chainCITE:E3.
EffectStory's semiconductor equipment data identifies ASML as the monopoly supplier of EUV and DUV lithography systems, ranked alongside Applied Materials, Lam Research, Tokyo Electron, and KLA as one of five major semiconductor equipment makersCITE:E4. Equipment supply is cited as one of the key bottlenecks constraining advanced-node production capacityCITE:E4.
EUV's exclusivity has turned the equipment itself into a geopolitical tool, with the United States leading restrictions on shipping EUV machines to ChinaCITE:E5. Those restrictions directly limit China's ability to independently develop advanced process nodesCITE:E5.
The next step after standard EUV is High-NA EUV, which uses a larger numerical-aperture optical system to further improve resolution and is positioned as the key equipment for process nodes below 2 nanometersCITE:E6. ASML leads in this next-generation technology as wellCITE:E6.
| Fact | Value | Source |
|---|---|---|
| EUV wavelength | 13.5 nanometers | CITE:E1 |
| Price per ASML EUV machine | Hundreds of millions of dollars | CITE:E3 |
| Major global semiconductor equipment makers | 5 (ASML, Applied Materials, Lam Research, Tokyo Electron, KLA) | CITE:E4 |
What this means: the same physical property that makes EUV light nearly impossible to work with — near-universal absorption requiring vacuum, mirror optics, and a laser-driven tin plasma sourceCITE:E2 — is what has left ASML as the sole producer capable of building these toolsCITE:E3. That single-supplier position, layered onto a five-company equipment landscape where ASML alone controls EUV and DUV lithographyCITE:E4, is also why export restrictions on EUV shipments function as a direct lever on advanced chipmaking capabilityCITE:E5, and why the shift toward High-NA EUV for sub-2-nanometer nodes keeps that same dependency running into the next generationCITE:E6.

The physics described here — a wavelength absorbed by nearly everything, forcing vacuum operation, mirror optics, and a laser-driven tin plasma source — is the real barrier to entry, not just capital. That is why a five-company equipment landscape still resolves to a single supplier for EUV and DUV specifically, and why advanced nodes below 2 nanometers stay bottlenecked on one vendor's roadmap rather than a competitive field. The technical indicator worth tracking is High-NA EUV adoption: since ASML leads that next-generation optical system as well, whether High-NA ships and scales on schedule will determine whether the single-supplier dependency simply carries forward into the next process generation or finally gets diversified.
NVIDIA reported Q2 FY2027 revenue of $96.2 billion, up 106% year-over-year and above the roughly $92 billion consensus, with Data Center revenue of $89.0 billion, up 117% and about 92% of total sales. Gross margin held at 75.0% and non-GAAP EPS of $2.22 beat the $2.10 estimate. Q3 guidance of $108.0 billion excludes any China Data Center compute revenue.
SpaceX plans to launch its first NVIDIA-chip-powered AI satellites, Starmind AI1, in the fourth quarter of 2027, reaching large-scale deployment by 2028 — at least a year ahead of the original schedule. The company has also filed with the FCC for a network of up to 1 million satellites, while Taiwanese suppliers Unitech and Sesoda report rising satellite-related revenue and order shares tied to the buildout.
NVIDIA announced the Jetson Orin Nano 2 robotics computer on August 25, 2026, packing 78 TOPS of AI compute, 8GB of memory, and an 8-core Arm CPU while doubling inference performance and cutting power draw 40% versus its predecessor. Modules and developer kits ship in the first half of 2027, targeting a robotics developer base NVIDIA says already tops 3 million.
