Samsung clears Tesla’s AI5 chip for fabrication on 2nm line

Samsung Foundry has confirmed that the Tesla ↗ 0.51% AI5 chip has reached tape-out on its 2-nanometer process line, clearing the design for fabrication at the company's Taylor, Texas facility. The milestone means Samsung has finished converting Tesla's chip blueprint into a manufacturable layout for its node and can now begin physically building the processor.evwire+1

From Design to Fab

The confirmation, reported on July 10, represents Samsung's own tape-out — distinct from Tesla's earlier design tape-out announced by CEO Elon Musk in April, when the AI5 blueprint was finalized. In semiconductor terms, a tape-out freezes a chip design and hands it off for manufacturing. Tesla's April announcement signaled the design was complete; Samsung's July confirmation means it has adapted that design for its specific 2nm process and production can now commence.electrek+1

Engineering samples of AI5 are expected late in 2026, with volume production not realistically arriving until mid-to-late 2027, according to EVwire. Tesla has said it wants several hundred thousand finished AI5 boards stockpiled before switching production lines, pushing meaningful in-vehicle deployment likely to 2028.evwire+1

A Lifeline for Samsung's Foundry Business

For Samsung, the Tesla contract comes at a critical juncture. The company's foundry unit has been posting quarterly losses of around 1 trillion won, and the Tesla orders — estimated at roughly $16.5 billion through 2033 covering both AI5 and the follow-on AI6 chip — represent a chance to revive the struggling division. The Taylor fab is set to begin operations anchored by Tesla's 2nm chips, positioning Samsung ahead of TSMC's Taiwan Semiconductor Manufacturing Company Limited ↘ 0.72% U.S. production capabilities for this particular contract.koreaherald+2

Musk confirmed during Tesla's Q3 2025 earnings call that both Samsung and TSMC will produce AI5, with TSMC handling a portion at its Arizona facility. The AI5 chip will serve as the core processor for Tesla's fifth-generation full self-driving hardware and is also expected to power its Optimus humanoid robot program.teslaacessories+3

What Comes Next

Beyond AI5, Samsung is also preparing to manufacture Tesla's AI6 chip on 2nm, which Musk has said will deliver roughly double the performance of AI5 at the same die size. An upgraded AI6.5 variant will be manufactured by TSMC in Arizona. However, Samsung's 2nm production timeline has faced challenges — a postponed multi-project wafer run earlier this year pushed AI6 mass production into late 2027.semiwiki+1

The tape-out marks one of the first confirmed 2nm designs heading into fabrication at Samsung's U.S. operations, a test of whether the Korean chipmaker can execute on advanced nodes as it competes with TSMC for the world's most demanding AI silicon contracts.
