Samsung Foundry Faces Yield Challenges and Delays in 2nm Production and Taylor Fab

Samsung's Foundry Challenges

Samsung Foundry is struggling with low yield rates for its first-generation 2nm process, reported to be around 55%. This yield level is below the threshold required for the business to operate advanced nodes profitably. The foundry unit's profitability was recently restored due to HBM4 logic-die orders, but it still significantly trails TSMC in revenue.

Taylor, Texas Fab Delays

The Taylor, Texas fab, a central component of Samsung's foundry roadmap, has experienced significant delays. Construction stalled through 2024 and into 2025, attributed to a lack of committed customers and yield problems. Equipment move-in occurred in April, with trial production targeted by the end of 2026 and full mass production in 2027, aiming for 50,000 wafer starts per month.

Reduced Funding and Tesla Contract

The CHIPS Act award for the Taylor project was revised down from up to $6.4 billion to $4.745 billion due to a narrowed project scope. Texas added approximately $250 million in state incentives. Tesla's AI6 processor, under a $16.5 billion contract signed in July 2025, is slated to be built at the Taylor facility. However, the AI6 chip's production has slipped by about six months, pushing volume toward late 2027 due to delays in engineering runs on Samsung's 2nm line.

Impact on Competition

Despite investments in new fabs and securing major contracts like the Tesla deal, Samsung's yield issues prevent it from closing the gap with TSMC. The company's ability to absorb these costs is partly due to its foundry unit being part of the Device Solutions division, which includes a profitable memory business, allowing it more operational runway than a pure-play foundry.
