In 2022, the CHIPS and Science Act promised a renaissance for U.S. semiconductor manufacturing. Fast forward to 2025, and it’s time to take a hard look: What’s real progress, and what’s still stuck in the pipeline?
Billions in subsidies, tax incentives, and R&D funding were designed to reduce U.S. dependence on foreign fabs—particularly in advanced nodes like 5nm and below. But has the U.S. truly moved the needle on fabrication competitiveness, or are we still shadowboxing with Asia’s foundry giants?
The Fabrication Footprint: What’s Actually Operational?
As of Q2 2025, only a handful of new fabs funded under the CHIPS Act are fully online. Intel’s Ohio mega-site, initially projected to start volume production in 2024, has pushed back key milestones to late 2025, citing equipment delays and skilled labor bottlenecks.
Meanwhile, TSMC’s Arizona fab has begun early-stage production—but it’s still manufacturing on N5 (5nm-class) nodes, not the bleeding-edge N3 or N2. According to recent industry benchmarks, yields and throughput remain below Taiwan levels, largely due to ecosystem immaturity and supply chain friction.
Node Leadership and Emerging Gaps
Despite CHIPS Act investments, the U.S. is not yet producing at scale below 5nm. Leading-edge nodes—3nm, 2nm, and projected gate-all-around (GAA) technologies—are still dominated by TSMC and Samsung, with primary operations based in Asia.
Intel’s 18A (1.8nm) process promises a return to leadership with RibbonFET and PowerVia innovations. However, volume ramp remains speculative, and any delay further widens the gap. Current data suggests U.S. fabs are at best two full nodes behind Asia’s most advanced capabilities.
AI Workloads and Foundry Pressure
AI is the wild card. The exponential growth in parameter counts (GPT-4 at 1T+, Gemini, and Claude v3) is driving unprecedented demand for high-performance, low-latency silicon.
This surge in demand should be an opportunity for U.S. fabs—but most AI accelerators are still fabbed at TSMC N3 or below. Even NVIDIA’s H100 and B100 chips rely on overseas nodes. Domestic fabs can’t yet offer competitive power efficiency or transistor density to meet AI workload demands.
Economic Ripple Effects
From an industrial standpoint, the CHIPS Act has triggered crucial wins:
- Reshoring of legacy node capacity (28nm and above), reducing automotive and defense sector vulnerability.
- Revival of semiconductor tool supply chains, especially in lithography and metrology.
- Increased investment in skilled workforce development through regional tech hubs.
- Greater transparency and coordination between federal agencies and semiconductor firms.
- Progress toward building a domestic ecosystem—but not yet a competitive edge at the bleeding edge.
So What?
The CHIPS Act is not a failure—far from it. But the narrative of instant scale-up and node parity was always unrealistic. Semiconductor manufacturing is a 10-year game, not a 10-month sprint. The U.S. has laid the groundwork to reenter the race, but it hasn’t crossed the starting line for advanced logic.
According to recent industry data, the U.S. share of global leading-edge capacity (defined as ≤7nm) remains under 10%. Without rapid progress at the sub-3nm level, the geopolitical and economic leverage of domestic fabs stays limited—particularly as AI, defense, and cloud players scramble for compute power.
Building fabs is not enough. The U.S. must also solve for talent, photomask supply, EDA tool competitiveness, and packaging innovation—areas still dominated by overseas players.
Key Takeaways
- The CHIPS Act catalyzed investment, but advanced-node production remains years away.
- U.S. fabs are critical for legacy and defense-related nodes, but not yet competitive for AI-grade silicon.
- Intel’s roadmap (18A and beyond) could close the gap—but execution risk is high.
- Global foundry leadership still resides in Asia, with meaningful U.S. gains contingent on sustained policy and commercial alignment.
- The economic impact is real but uneven—reshoring is happening, but leadership is still aspirational.
What will it take for the U.S. to truly lead in sub-2nm semiconductor manufacturing—and can we afford to wait?
