Samsung Taylor Fab

Overview

The Largest Chip Investment in Texas History

Fab 1 is Tesla's; Fab 2 and beyond are merchant fabs for other customers.

Samsung Foundry is building its 2nm gate-all-around (GAA) logic fab on 1,200 acres in Taylor, Williamson County, with more than $45B committed across announced phases. Fab 1 started as a $16.5B 4nm fab; Samsung moved it to first-generation 2nm midway through construction, taking its capital to $37B to $44B. The campus plan runs to as many as ten fabs.

Samsung Taylor is one of the three manufacturing supernodes of the Austin Supercluster, with Tesla Giga Texas and the SpaceX Bastrop campus. Fab 1 is a Tesla-only fab: a $16.5B contract signed in July 2025 runs through 2033 for AI5 and AI6, and Tesla engineers work on the fab floor. Fab 2 and every fab after it are merchant fabs open to other customers.

The supplier ring

The Samsung Taylor Supplier Ring

Each supplier is placed by how close it sits to the fab and what it supplies. Select one for its detail; the filters drive the ring and the table.

The ring maps 79 suppliers in three tiers. Production inputs (Tier 1A) are the gases, chemicals, photomasks, wafers and sputtering targets the fab consumes, with Tesla counted as anchor wafer demand. Co-located infrastructure (Tier 1B) is the water supply, reclamation, ultrapure water, logistics and the Oncor substation. Equipment and construction (Tier 2) is the general contractors, the wafer fab equipment makers from ASML to Tokyo Electron, and the EDA tool vendors.

32 of the 79 sit on the Samsung campus or in the Austin metro. The hardest-to-replace inputs are the farthest away: EUV lithography from ASML in Veldhoven, EUV mask blanks from Hoya, actinic mask inspection from Lasertec and EUV photoresist from JSR, all sole or dominant sources.

Shared across anchors

Suppliers Shared With Other Texas Anchors

The same companies turn up around Giga Texas, Starbase, Brookshire and Meta Temple. Linde, for example, appears in six anchor rings including this one.

AustinIO maps supplier rings for 10 other Texas anchors. 6 suppliers serve five or more of them: Air Liquide, Caterpillar, Hitachi Energy, Linde, Quanta Services and Schneider Electric. These are the gas, power and construction companies the whole buildout runs on.

Tesla Giga Texas shares the most with Taylor: 20 companies, from the gas companies to ASML, Applied Materials, Lam Research and KLA.

The Korean contingent

Samsung Brought Its Korean Supply Base

Construction, captive tools, chemicals, gases, piping and logistics, from Korean companies that followed Samsung to Texas.

Samsung moved its Korean stack to Central Texas. Samsung E&C America (SECAI) and Samsung C&T run construction, SEMES supplies captive tools, and 15 Korean companies in the ring have sited plants, offices or logistics in the region: Soulbrain and the 212-acre iMarket supplier park in Taylor, Fine Semitech in Hutto, KoMiCo in Round Rock, Hanyang ENG in Cedar Park, Wonik Materials in Manor, Dongjin Semichem in Killeen and LS Electric in Bastrop.

TSMC Arizona builds with Western contractors such as Exyte. Taylor runs on Korean firms from construction through chemicals and logistics, the way Samsung operates at Pyeongtaek and Hwaseong. Samsung has run its Austin fab on Parmer Lane since 1997, and that sister site feeds Taylor its workforce and vendors.

At the doorstep

Data Centers at the Fab Gate

Taylor and Hutto are filling with AI data centers within a few miles of the fab.

The US 79 corridor puts chip fabrication and AI compute side by side. KDC's Project Comal, Project Mustang and Blueprint are in Taylor; Skybox's 600 MW PowerCampus, Colovore's Project Raptor and an Iron Mountain campus are in Hutto, one exit west. Farther out along US 79, Riot Rockdale and Stargate Milam sit on the old Alcoa ground in Milam County.

The corridor's fabs and data centers share the same transmission, the same Milam County water and the same construction trades. See the US 79 Data Center Corridor for the full set.

The Texas silicon chain

Design, Fab, Package, Launch

Design at Tesla in Austin, fabrication at Taylor, advanced packaging at SpaceX Bastrop and integration at Starbase: each step of an AI chip's path sits in Texas, and Taylor is the fabrication node. Silicon from Taylor flows to Giga Texas for vehicles, Optimus and the Cortex training clusters, and AI silicon fabricated here can be packaged at Bastrop for Starlink and Starshield.

The dependency runs both ways in AustinIO's data: Samsung Taylor appears in the Tesla Giga Texas supplier ring, and Tesla appears in this one as anchor demand.

Constraints

Water and Power

Water. EPCOR's $300M+ Sandow pipeline draws Carrizo-Wilcox aquifer water from Milam County, and the on-site Blue Sky reclamation plant targets 75% process-water reuse. T1 Energy's G2 Austin plant and SB Energy's Stargate Milam campus draw on the same county's water. See Texas Water Supply and Stress.

Power. The fab is grid-tied through Oncor's Taylor substation. Leading-edge process tools need power quality that on-site generation struggles to deliver, so Samsung runs on the grid with power conditioning, unlike the behind-the-meter data centers around it.
