A report outlines how Apple and its suppliers are rebuilding parts of the U.S. chip supply chain, from silicon wafers in Texas to final assembly in Houston. The strategy centers on strengthening supply resilience after pandemic shortages and rising tension around Taiwan. However, Apple's most sophisticated silicon chips still rely on Taiwan's advanced manufacturing technology, as the U.S. expansion functions more as insurance against geopolitical disruption than a replacement for Taiwan's leading capabilities.

Why it matters

Apple's push to expand semiconductor manufacturing in the U.S. is mainly aimed at reducing geopolitical risk, rather than bringing back large-scale factory jobs. The move highlights the challenges of replicating Taiwan's leading chip fabrication expertise and production scale within the U.S. in the near term.

The details

The domestic pipeline begins in Sherman, Texas, where purified silicon is melted and formed into 12-inch wafers. Those wafers are then shipped to Taiwan Semiconductor Manufacturing Co.'s (TSMC) Arizona fab, where they are etched into logic chips. TSMC's Arizona campus is part of a massive investment plan, but the latest and most advanced Apple Silicon chips still rely on Taiwan's leading manufacturing technology. Advanced packaging, a key step, also remains a major gap in the U.S. supply chain. Apple's most visible U.S. assembly efforts are concentrated in Houston, where Foxconn assembles servers and Mac minis, but the workforce is small compared to Apple's massive iPhone assembly complexes in Asia.

  • In February 2026, a report outlined Apple and its suppliers' efforts to rebuild parts of the U.S. chip supply chain.
  • TSMC's Arizona fab is expected to begin production in 2028.

What’s next

Amkor's multibillion-dollar advanced packaging campus in Arizona is expected to begin production in 2028, which could help reduce the need to send chips overseas for packaging.

The takeaway

While Apple is expanding semiconductor manufacturing in the U.S. to reduce geopolitical risk, Taiwan remains central to the production of Apple's most sophisticated silicon chips in the near term. The U.S. expansion functions more as insurance against disruption than a replacement for Taiwan's leading capabilities.
