Four years after the U.S. CHIPS and Science Act was signed, the program is beginning to show measurable results in semiconductor manufacturing. The full $39 billion in direct manufacturing subsidies has now been allocated, with 23 recipients receiving funding commitments and about $11 billion already paid out based on project milestones.
The CHIPS Act has helped move several U.S. fab projects from planning into production. As a result, the key question for engineers and procurement teams is no longer if or when the new U.S.-based capacity will become available. The more practical question now is how this new capacity is affecting supply chain resilience, sourcing strategy and long-term component cost.
Quick Takeaways
- U.S. advanced logic capacity is expanding, with three subsidized logic fabs already in production.
- The U.S. share of advanced logic manufacturing has reportedly increased from about 12% in 2020 to roughly 22% in 2026.
- The remaining challenge is operating cost, not just construction cost.
- For sourcing teams, the likely result is more geographic redundancy, not a replacement of Asian semiconductor supply chains.
U.S. Fab Capacity Is Moving from Plans to Production
The most visible result of the CHIPS Act is new fab capacity entering production. Three subsidized advanced logic fabs have reached mass production: TSMC’s Arizona Fab 21 Phase 1 on 4nm, Intel’s Ohio Module 1 on 18A, and Samsung’s Taylor, Texas Fab 1 on 3nm GAA.
Another 12 subsidized wafer fab projects remain under construction, with production starts expected between late 2026 and 2029. This means the CHIPS Act is moving beyond subsidy announcements and into actual manufacturing output.
That matters for component sourcing because semiconductor production is becoming more geographically distributed. TSMC’s Arizona facility is producing chips for customers including Apple and Nvidia, while advanced packaging projects, including TSMC’s CoWoS-related facilities and SK Hynix’s HBM packaging project in Indiana, are intended to bring more of the manufacturing chain into the U.S.
Supply Chain Resilience Is Improving, but Asia Remains Central
The CHIPS Act is improving supply chain resilience by adding U.S.-based capacity for advanced logic and advanced packaging. This gives customers another regional option for strategically important chips and reduces some reliance on a single manufacturing geography.
The arrival of additional domestic semiconductor production capacity can deliver benefits for U.S.-based buyers. The U.S. ranks second behind China in terms of global electronic component procurement in the catalog distribution segment, according to the Supplyframe Commodity IQ Sourcing Activity Index. The U.S. index score has risen significantly this year, increasing to 91.1 in July, up from 75.1 in January, indicating intensifying purchasing activity in the country.
At the same time, the U.S. represents a relatively small percentage of global electronic component production. For example, the share of semiconductor manufacturing capacity located in the U.S. totaled just 10% of the global total in 2022, according to SEMI.
The establishment of new U.S. capacity is helping to slightly reduce the gap between domestic demand and supply levels, providing a new source of supply with less exposure to the uncertainties of tariffs and trade disputes. However, the arrival of more U.S. manufacturing capacity cannot even come close to fulfilling all the U.S.’s needs.
As a result, the new U.S. capacity does not replace Asia’s role in semiconductor manufacturing. The three operating U.S. advanced logic fabs together have monthly capacity of about 69,000 wafers, which remains small compared with major Asian manufacturing hubs.
For procurement teams, this suggests the CHIPS Act should be viewed more as a resilience mechanism than a cost-reduction mechanism. U.S. capacity adds another supply option, but it does not eliminate the need for Asian manufacturing relationships.
The Cost Issue Has Shifted from CapEx to OpEx
The CHIPS Act can help offset capital expenditure, but it does not fully solve operating economics. Building a fab in the U.S. can cost 30% to 50% more than a comparable facility in Taiwan, operating costs can be 30% to 40% higher, and finished wafer costs may be 20% to 30% higher.
Several factors contribute to that gap, including higher engineering labor costs and continued dependence on imported ultrapure water systems, specialty gases, chemicals, and other manufacturing inputs.
That cost structure matters downstream. If U.S.-made wafers remain structurally more expensive, buyers should not assume that domestic production will automatically lower component pricing. In some cases, U.S.-based capacity may function more like a premium supply assurance option.
What Engineers and Procurement Teams Should Expect
For engineers, the main implication is greater attention to manufacturing location and long-term supply qualification. As more fabs come online, design teams may have more options for qualifying components across different regions, but those options may differ in cost, availability, and production timing.
For procurement teams, the clearest takeaway is that dual-source and multi-region sourcing strategies are likely to become more important. U.S. capacity is unlikely to fully replace Asian capacity, but it is becoming an expensive and increasingly necessary second leg of the semiconductor supply chain.
The Bottom Line
Four years into the CHIPS Act, the U.S. has made measurable progress in rebuilding advanced semiconductor manufacturing capacity. The program has improved geographic diversification and strengthened supply chain resilience, but it has not erased the cost gap between U.S. and Asian manufacturing.
For component sourcing, the practical outcome is clear: expect more regional supply options, more emphasis on dual sourcing, and continued pricing trade-offs where supply assurance carries a premium.
