The Procurement Outreach: Quotes Requested from the Big Three

Staff working on Elon Musk's Terafab project have reached out to Applied Materials Inc., Tokyo Electron Ltd., and Lam Research Corp. seeking price quotes and delivery timelines for chipmaking equipment, Bloomberg reported on April 15, 2026. The outreach — confirmed by multiple industry sources and covered by Tom's Hardware and Taipei Times on April 17 — marks the transition of the $25 billion Tesla/SpaceX/xAI chip fabrication venture from concept to active procurement.

The contacts represent the first known formal engagement with the semiconductor equipment supply chain since Musk announced Terafab at Giga Texas in Austin in late March 2026. Applied Materials, Tokyo Electron, and Lam Research collectively account for the majority of global plasma etch and thin film deposition tool shipments, making their inclusion in the outreach a direct signal that Terafab is targeting leading-edge fabrication processes.

Equipment Sought: Etchers, Depositors, Photomasks, Substrates

According to Bloomberg's reporting, Terafab representatives have contacted suppliers of photomasks, substrates, etchers, deposition systems, cleaning equipment, and testing devices. The breadth of the inquiry covers virtually the entire semiconductor manufacturing tool set, from front-end wafer processing through back-end test. However, suppliers report being given minimal information about the specific products to be manufactured, which analysts say reflects the project's early and still-evolving technical state.

The explicit inclusion of etchers and deposition systems in the outreach is significant. At the 2nm process node Terafab is targeting — using gate-all-around (GAA) nanosheet transistors — plasma etch and thin film deposition tools account for the single largest share of front-end equipment spending. GAA nanosheet fabrication requires dozens of precisely timed etch steps for nanosheet channel release, spacer definition, and contact formation, plus hundreds of deposition steps for high-k gate dielectrics, work-function metals, barrier layers, and low-k interlayer dielectrics.

Paying a Premium to Jump the Queue

Terafab's team is offering to pay "considerably above quoted amounts" if equipment suppliers give the project delivery priority, Bloomberg reported. The willingness to pay a premium reflects both the urgency of Musk's timeline and the reality of a semiconductor equipment market where lead times for critical tools already stretch 12–24 months, driven by TSMC's $56 billion 2026 capex program, Samsung's aggressive HBM4 ramp, and ongoing capacity expansions at Intel, Micron, and SK Hynix.

In one documented exchange, a Terafab representative contacted a supplier on a Friday holiday asking for pricing estimates by the following Monday — an unusually compressed timeline that sources described as consistent with Musk's standing instruction to move at "light speed." No formal purchase orders have been placed; the outreach is currently at the request-for-quote (RFQ) stage.

Samsung Responds with Capacity Instead of Hardware

Samsung Electronics declined to provide equipment quotes and instead proposed offering Tesla additional foundry capacity at its planned Texas manufacturing facility as an alternative to Terafab building its own fab. The counteroffer — essentially a "let us make the chips for you" response — was not accepted, and Terafab's procurement outreach continues independently.

Samsung's position highlights the tension between established foundries, which prefer to keep leading-edge capacity utilization within their own walls, and Terafab's stated goal of vertically integrating chip design, wafer fabrication, memory, and packaging under a single roof. The divergence is unlikely to be resolved in the near term, as Musk has explicitly stated that current global foundry supply covers only about 2% of his companies' combined chip needs.

Scale and Timeline: 3,000 Wafers a Month to Start

Terafab is targeting a pilot phase of 3,000 wafer starts per month, with silicon manufacturing aimed at beginning by 2029. Full-scale production — originally described as potentially scaling to 1 million wafer starts per month — would require equipment orders of a magnitude the industry has never seen from a single customer. Bernstein analysts have estimated the complete Terafab buildout at $5 trillion to $13 trillion in total capital spending, though those figures encompass multi-decade, multi-facility projections rather than near-term commitments.

Even the pilot phase at 3,000 wafers per month at 2nm would require roughly 40–60 plasma etch chambers and a similar number of deposition reactors. Scaling to the stated 100,000 wafer-starts-per-month first milestone would require roughly 1,500–2,000 etch and deposition chambers, comparable to a mid-size TSMC fab complex. At the full 1 million wafer-starts scenario, the equipment requirement would exceed the combined installed base of most existing leading-edge fabs worldwide.

What This Means for Plasma Processing and Thin Film Deposition

The Terafab procurement outreach places new pressure on an equipment supply chain already running near full capacity. Applied Materials, contacted directly by Terafab, is the world's largest supplier of CVD, PVD, and etch equipment, with its Sym3 Z plasma etch platform and Trillium ALD system established as tools of record at the 2nm node. Lam Research, also contacted, is the leading supplier of high-aspect-ratio plasma etch and its ALTUS Halo molybdenum ALD system has recently entered production. Tokyo Electron supplies plasma thermal processing tools and is a significant player in deposition and etch for advanced logic.

For plasma processing equipment specifically — including inductively coupled plasma (ICP) etch, capacitively coupled plasma (CCP) etch, PECVD, and plasma activation systems — the Terafab outreach adds a new, high-profile demand signal atop an already saturated backlog. Upstream supply chain components including RF generators, plasma sources, electrostatic chucks, process gas delivery systems, and ceramic chamber coatings face cumulative pressure from simultaneous ramp-ups across TSMC, Samsung, Intel, and now Terafab.

For thin film deposition — ALD, CVD, PVD, and sputtering — the signal is equally pointed. GAA nanosheet manufacturing at 2nm is extremely ALD-intensive, with each wafer requiring more than 100 distinct deposition steps. ALD precursor supply, vacuum component lead times, and high-purity process gas availability are all potential bottlenecks if Terafab's pilot phase launches on schedule in 2029. The broader implication is that equipment suppliers now face a five-party demand structure — TSMC, Samsung, Intel, Micron, and Terafab — all competing for prioritized delivery of the same tools at the same node.
