Five Key Challenges for Increasing
U.S. Domestic Semiconductor
Manufacturing Capacity

White Paper Abstract

TThis whitepaper provides semiconductor industry stakeholders, policymakers, and technology leaders with a framework for understanding the structural challenges facing the effort to rebuild domestic chip manufacturing capacity. As the U.S. moves to reverse decades of offshored fabrication, five distinct obstacles, spanning technical capability, R&D investment, market alignment, workforce economics, and measurement infrastructure, will determine whether investment translates into durable manufacturing capacity. Since this analysis was first published, an unanticipated force has reshaped the landscape faster than any policy could: AI-driven demand has pushed the industry’s growth trajectory years ahead of its own 2022 forecasts, even as some flagship CHIPS Act-backed projects have slipped years behind schedule, and the policy landscape itself is now shifting again, with a key tax incentive set to expire at the end of 2026. Understanding both forces, demand and policy, is essential for any organization positioning itself within the reshoring effort.

What You Will Learn About Semiconductor Manufacturing Capacity

• Why no global region, including the U.S., currently possesses true end-to-end semiconductor design and manufacturing capabilities, and where domestic semiconductor manufacturing capacity capacity is furthest behind.
• How the widening cost of leading-edge fabrication, now exceeding $5 billion to outfit a facility for advanced nodes, raises the stakes for R&D prioritization and technology roadmap decisions.
• Why different end markets (automotive, aerospace, military, clean energy) impose conflicting requirements on chip production, and why manufacturer-customer collaboration is critical to avoiding misaligned capacity.
• How labor costs and workforce shortages, projected to require 70,000 to 90,000 additional fab workers, remain one of the two competitive factors where the U.S. still lags.
• Why traditional contact-based thermal testing cannot meet the resolution and throughput demands of modern thin-film semiconductor manufacturing, and what a non-contact alternative looks like.
• Why AI demand, not federal policy, has driven the sharpest divides in reshoring outcomes, and how much of the CHIPS Act’s $39 billion manufacturing incentive pool has actually been disbursed as of 2026.
• What’s at stake in the looming expiration of the Advanced Manufacturing Investment Credit, and which industry groups and lawmakers are pushing to extend it before the end of 2026.

White Paper Preview: The Five Key Challenges

The United States now produces a shrinking share of the world’s leading-edge chips by manufacturing capacity, even as U.S.-headquartered companies hold more than half of global semiconductor revenue, a gap that reflects America’s continued strength in design and its persistent weakness in fabrication. The CHIPS and Science Act helped catalyze a wave of new fabrication investment, but four years on, it’s demand, not policy, that has done the heavier lifting: AI infrastructure and data center buildouts have driven the global semiconductor market toward $1 trillion in annual sales years earlier than the original 2022 forecasts anticipated, with McKinsey’s most recent base case now projecting $1.6 trillion by 2030, roughly 60% above its original estimate.

That demand has split the reshoring effort into two distinct stories. TSMC’s Arizona investment has grown from an initial $12 billion to $265 billion, with fabs coming online on or ahead of schedule. Micron’s $250 billion-plus U.S. investment through 2035 broke ground and began construction months ahead of its own internal timeline. Meanwhile, Intel’s Ohio project, once the highest-profile symbol of the CHIPS Act, has slipped roughly five years from its original 2025 target, and Samsung’s Taylor, Texas fab has moved from a planned 2024 opening to likely 2027, in both cases because of insufficient customer demand for the leading-edge chips these facilities were built to produce, not funding delays.

This guide examines five key challenges among the most significant structural barriers to scaling domestic capacity: building genuine end-to-end manufacturing capability, sustaining R&D investment against a backdrop of rapidly escalating fabrication costs, aligning new capacity with the divergent requirements of automotive, aerospace, and clean energy customers, closing a labor gap that could reach 300,000 workers under full self-sufficiency scenarios, and modernizing thermal testing infrastructure to keep pace with shrinking device geometries. It closes with a dedicated policy update: where the CHIPS Act’s manufacturing incentives actually stand after a slow rollout and a recent shift from grants to government equity stakes, and why a second, more urgent deadline, the AMIC’s expiration on December 31, 2026, has drawn a bipartisan push in Congress and a coalition of industry groups warning that $640 billion in announced investment is riding on the outcome.
