Terafab is reportedly expected to receive its first extreme-ultraviolet (EUV) lithography scanner from ASML in mid-2027. That date comes from a 14 October 2026 Tom’s Hardware report citing analyst Tim Culpan and people familiar with the project. It is a delivery expectation, not a publicly confirmed ASML order, quoted price, named scanner model or binding schedule.
The timing could create an unusual gap: the development-fab shell in Grimes County, Texas, may not be complete until late 2027. The scanner could therefore remain idle for months before installation, utilities, cleanroom systems and commissioning are ready.

What is known about the reported EUV delivery
The reported mid-2027 arrival refers to Terafab’s first EUV tool. EUV scanners project extremely short-wavelength light through a photomask to print the smallest features on advanced chips. In this case, the report says Terafab’s first-generation effort will use conventional, low-numerical-aperture EUV equipment rather than the free-electron-laser light source Elon Musk has discussed.
Nothing in the public reporting establishes which ASML scanner model is involved, the purchase price, a signed delivery contract or a firm installation date. “Receive” could describe delivery to the project rather than a production-ready tool operating on wafers.
Why the scanner could arrive before the fab is ready
Tom’s Hardware places the development-fab shell’s completion in late 2027, several months after the reported EUV delivery window. A delivered scanner cannot run simply by being parked inside an unfinished building. The site still needs completed cleanroom construction, vibration control, power, water, specialty gases, exhaust, chemical handling, software integration and process qualification.
That sequence makes a temporary idle period plausible. The report says tools would begin moving in later in 2027, so the scanner might be stored or held pending installation and commissioning while construction and equipment fit-out continue.
What Terafab is intended to build
Terafab is a planned semiconductor-manufacturing initiative associated with SpaceX, Tesla and xAI. Reuters describes two intended advanced-chip factories: one supplying Tesla vehicles and Optimus humanoid robots, and another aimed at artificial-intelligence data centers in space. Musk presented the project as a response to expected chip shortages within his companies.

SpaceX’s 2026 EU prospectus describes Terafab, together with Tesla, as a manufacturing initiative capable of producing 1 terawatt of compute hardware per year. That is a stated long-term capacity objective, not evidence that the Texas site has reached production.
Planned process technology: Intel 14A
Reuters reports that Tesla plans to use Intel’s 14A manufacturing process. The reported equipment choice is consistent with a first-generation fab using existing low-NA EUV scanners. Intel’s 14A is expected to use those scanners alongside next-generation high-NA EUV machines, but the reporting does not establish Terafab’s eventual high-NA equipment plans.
Using a named process does not by itself prove that Terafab has qualified it. A production line would still need to demonstrate yield, design-rule compliance, reliability and sufficient throughput for automotive, robotics and AI workloads.
Where the facilities are planned
The large-scale Terafab facility is planned for Grimes County, Texas. Tesla is also building a smaller research fab at the north campus of Giga Texas. The two sites should not be treated as the same project phase: the research facility may support development work, while the Grimes County campus is the proposed high-volume manufacturing site.
Scale and capital requirements
The announced initial phase requires $16.8 billion and envisions more than 100 million square feet of manufacturing space. Tom’s Hardware cautions that this figure is total manufacturing space, not 100 million square feet of cleanroom floor. Cleanrooms are only one part of a semiconductor campus; utilities, logistics, offices, warehouses, packaging and testing areas also consume substantial space.
Reuters reports that total investment could reach $119 billion if later phases are completed. That larger number is a possible full-program investment, not the amount committed to the first construction phase.
Rank #4
The campus is envisioned as vertically integrated, combining logic fabrication, memory, packaging and testing. Keeping those operations together is intended to shorten production cycles and make design and process changes faster, but it also increases the number of complex manufacturing systems that must be built, qualified and operated successfully.
Reported schedule versus what remains uncertain
| Milestone | What the reporting says | Qualification |
|---|---|---|
| First ASML EUV tool | Expected in mid-2027 | Tom’s Hardware report from 14 October 2026; no public ASML confirmation, model, price or binding date |
| Development-fab shell | Expected in late 2027 | Could leave the scanner idle until construction and fit-out are complete |
| Initial investment | $16.8 billion | Figure attributed to the SpaceX/Tesla announcement as reported by Tom’s Hardware |
| Planned manufacturing space | More than 100 million square feet | Manufacturing space, not equivalent cleanroom space |
| Potential investment through later phases | Up to $119 billion | Reuters figure if additional phases proceed |
| Start of operation | Late 2029 | Estimate quoted from SemiAnalysis by Tom’s Hardware |
| Volume ramp | Mid-2030 | Estimate quoted from SemiAnalysis; not a guaranteed production date |
Reuters says SpaceX has not assured that Terafab will meet its objectives within the expected timelines—or at all. Open questions include who will pay for the equipment, who will operate the factory and when it will actually come online. Those uncertainties matter more to chip availability than the arrival of a single scanner.

- Complete the building and cleanroom: The shell, controlled environment and supporting infrastructure must be finished.
- Install and qualify the scanner: Engineers must connect utilities, align the tool, verify overlay and focus performance, and integrate factory-control software.
- Bring in the rest of the line: Lithography is only one step. Deposition, etch, cleaning, metrology, inspection, ion implantation, masks, substrates, packaging and test equipment are also required.
- Run process development wafers: Teams must tune Intel 14A-related recipes, measure defects and improve yield.
- Reach volume production: Customer designs need qualification and the line must sustain acceptable yield, throughput and reliability.
Reuters reports that Terafab staff sought quotations and delivery times for photomasks, substrates, etchers, deposition, cleaning, testing and other equipment. That indicates planning across the broader line, but requests for quotes are not proof that every purchase has been completed.
Best Value
So when will Terafab actually make chips?
The most specific public estimate is late 2029 for operations to begin, with a volume ramp by mid-2030. Those dates are estimates, not commitments. The reported EUV delivery in mid-2027 is an equipment milestone, while useful chip output depends on construction, installation, process qualification, staffing, financing and yield.
Musk summarized the strategic pressure at an Austin presentation by saying, “We either build the Terafab or we don’t have the chips.” The statement explains the project’s motivation, but it does not change the distinction between an announced objective and a functioning foundry.
Bottom line for readers
Yes—based on the October 2026 report, Terafab is expected to get an ASML EUV scanner around mid-2027. No—there is not yet public confirmation of an ASML contract or proof that the tool will be making chips then. The scanner may arrive before the development fab is ready, and the earliest cited production estimates place initial operation in late 2029 with volume ramping in mid-2030.
