Samsung Taylor Fab Trial Runs Reportedly Could Start in December

Samsung Electronics could begin trial operations at its first Taylor, Texas foundry fab around mid-to-late December 2026, the Korea Herald reported on Nov. 8, citing industry sources. Samsung has not confirmed a date.

According to the Korea Herald, Samsung has been installing manufacturing equipment, setting up production lines and running performance checks at the plant. Samsung Austin Semiconductor, its US manufacturing subsidiary, is also hiring engineers for etching, metallization and ion implantation, plus technical instructors to train new staff. Samsung spokesperson Michele Glaze told the San Antonio Express-News on Oct. 27 that the first Taylor fab will be fully operational by the end of 2026, and the Herald says she confirmed the same timetable in late October. A December trial start would fit that year-end target, though Samsung has not linked the two.

The date matters because a trial run is the step before yields can be judged, and the Herald notes that Samsung must still stabilize yields on its 2-nanometer process, and it gives no yield figure. The fab began construction in 2022 and was first aimed at the second half of 2024, so the start has slipped by about two years.

What Taylor is expected to build

The Herald says the plant is expected to make Tesla's next-generation AI6 chips under a $16.5 billion supply agreement announced last year, with chip production planned for the second half of 2027. Seoul Economic Daily reported a different picture on Sept. 15: that Taylor had already started 2nm trial production, for Tesla's AI5 chip, with mass-production verification due by year-end. Both accounts rest on unnamed industry sources, and Samsung has confirmed neither. Samsung told investors on its Oct. 29 call that major-customer 2nm volume starts in the second half of 2027, as Voltgrid reported.

Samsung is also moving to a second Taylor plant. Glaze said on Oct. 27 that construction on the second fab starts in November and that it is planned to be operational by 2030. The Herald adds that the second plant has reportedly won orders for logic base dies for HBM chips destined for AMD and NVIDIA, which Samsung has not confirmed; we covered that earlier report on 2nm HBM base dies.

How far behind Samsung still is

Samsung remains a distant second in contract chipmaking. TrendForce put its share of global foundry revenue at 5.9% in the second quarter, against 72.5% for TSMC, as quoted by the Herald. Taylor's output is planned to ramp only in 2027, so it is a signal for next year's foundry share, not this year's.

What is not confirmed yet

Samsung has not said when trial operations begin, which chip is running first, or what yields it is seeing. The Herald's December window, the September trial-production claim and Samsung's own year-end "fully operational" wording describe different stages, and none of the three has a Samsung-published date. The next firm signals would be a Samsung statement on the start of operations and any customer announcement tied to Taylor wafers.
