Is American Manufacturing Actually Coming Back? TSMC Arizona, CHIPS Act, and the Real Story Behind the Reshoring Hype

In February 2024, TSMC's first Arizona fab — Fab 21 — began producing chips on 4nm process technology. In March 2026, the facility is ramping toward full production. Apple has publicly confirmed it is using chips from TSMC Arizona in certain product lines. For the first time since the 1990s, leading-edge semiconductor chips are being manufactured in the United States. The moment carries genuine symbolic and strategic weight: the most advanced chips in the world, previously made almost exclusively in Taiwan — 50 miles from mainland China — are now being produced on American soil. Whether this constitutes a manufacturing renaissance or an expensive, partial hedge against geopolitical risk depends on who you ask — and what metrics you use.

The Semiconductor Situation: What CHIPS Act Is Actually Doing

• TSMC Arizona (Fab 21 and Fab 22): Fab 21 produces 4nm chips — the same generation used in current iPhone and Mac processors. Fab 22, targeting 2nm production starting in 2028, is under construction. TSMC received $6.6 billion in CHIPS Act direct funding plus $5 billion in loans. The total planned Arizona investment is $65 billion.
• Intel Ohio (New Albany): Intel's Semiconductor Manufacturing campus in Ohio is the largest semiconductor manufacturing investment in US history at a planned $100 billion across multiple fabs. The first fab is targeted for production by late 2026. Intel received $8.5 billion in CHIPS Act direct funding.
• Samsung Texas (Taylor): Samsung's Taylor, Texas fab broke ground in 2022 and is targeting advanced chip production in 2026. Samsung received $6.4 billion in CHIPS Act funding.
• The cost reality: American fab production costs are estimated at 30-50% higher than equivalent production in Taiwan or South Korea, due to land costs, labor costs, supply chain costs, and the lower density of the US semiconductor ecosystem. The CHIPS Act funding offsets some of this gap but does not eliminate it.
• The workforce problem: semiconductor manufacturing requires a highly specific workforce — engineers, technicians, and operators with training in cleanroom operations and semiconductor physics. The US semiconductor manufacturing workforce largely dissolved over 30 years of offshoring. Rebuilding it is taking longer than the fabs themselves. TSMC, Intel, and Samsung have all faced workforce challenges in their US facilities.

The Tariff Effect: Are Tariffs Actually Reshoring Manufacturing?

The Trump administration's 2026 tariffs — covering goods from China, Mexico, Canada, and dozens of other trading partners — are the largest US trade policy intervention since the Smoot-Hawley Tariff of 1930. Their intended effect is to make imported goods more expensive, incentivizing companies to manufacture domestically. The reality, as with most large economic policy interventions, is more complex and more mixed.

• What tariffs have actually reshored: labor-intensive manufacturing where the tariff cost exceeds the offshore labor cost advantage is most affected. Some furniture, appliance, and consumer electronics assembly has returned to US production, primarily in Southern states with lower labor costs.
• What tariffs have not reshored: advanced electronics, semiconductor assembly, and precision manufacturing — the high-value manufacturing categories the US most needs — require not just labor but deep supply chain ecosystems. A Chinese factory making iPhones doesn't just need labor; it needs 200 specialized component suppliers within a 100-mile radius. Tariffs on Chinese goods do not instantly create those supply ecosystems in Ohio.
• The nearshoring alternative: much reshoring activity is actually nearshoring — moving production from China to Mexico, Vietnam, or India. These countries face lower or zero tariffs under current policy, so companies can avoid the tariff impact without US domestic investment. Apple accelerated iPhone production in India. Many electronics manufacturers moved to Vietnam. The job gains from this activity go to Mexico, India, and Vietnam — not to American workers.
• The consumer price impact: tariffs are primarily paid by US importers, who pass them to consumers. Estimates for the consumer price impact of current tariff levels range from $800 to $3,800 per American household annually, depending on assumptions about which goods are affected and how much cost is absorbed versus passed through.

The Jobs Question: How Many Manufacturing Jobs Are Actually Coming Back?

Political messaging around manufacturing reshoring consistently overstates the job creation impact. The reasons are structural and important to understand.

• Modern manufacturing is automated: a semiconductor fab employing 2,000 workers in 1985 requires fewer than 500 workers today using modern automated equipment. The manufacturing jobs of the 21st century require STEM skills and carry higher wages than the assembly line jobs they replace — but there are far fewer of them.
• CHIPS Act jobs: the semiconductor investments funded by the CHIPS Act are projected to create approximately 115,000 total jobs — direct manufacturing employment plus supply chain and induced employment. This is meaningful but not transformative at the macro scale of the US labor market (165+ million workers).
• Where job creation is concentrated: the manufacturing revival is creating meaningful employment in specific geographic locations — Phoenix metro (TSMC), Central Ohio (Intel), and Taylor TX (Samsung). These regions are experiencing genuine economic development. The national jobs number is more modest.
• The skills premium: the jobs being created by advanced manufacturing reshoring pay significantly above median wages — average semiconductor fab technician roles at $60,000-$90,000, engineer roles at $100,000+. The quality of jobs created is higher than the quantity, which is an honest argument for the policy even if the headline job numbers are modest.
