Abstract: Semiconductor manufacturing is becoming more geographically distributed, but not displaced. This blog explains why foundries and IDMs are expanding into new regions, what changed after 2020, and why this trend reflects risk management and customer alignment rather than a shift away from core ecosystems.

A Shift in Geography That Looks Dramatic, But is Not What it Seems
Over the past several years, the global semiconductor industry has begun to look different on a map. New fabs are being announced in the United States, Japan, Europe, India, and Southeast Asia. Integrated device manufacturers are expanding production footprints closer to customers. Foundries that once concentrated nearly all advanced manufacturing in a single geography are now carefully replicating pieces of that capacity elsewhere.
To many observers, this looks like a sudden shift driven by geopolitics or trade policy. In reality, what is happening is a rational and incremental response to a more volatile world since 2020. The semiconductor industry is diversifying geographically, but it is not relocating its core. That distinction matters.
Geographic Diversification is Not New
Semiconductor manufacturing has always had a geographic dimension. Even companies most closely associated with a single country have long operated internationally. Taiwan Semiconductor Manufacturing Company established its first overseas manufacturing presence in the late 1990s with WaferTech in Washington State. That facility focused on mature nodes and specialty production, not advanced logic.
Intel has operated fabs and assembly sites across the United States, Europe, Israel, and Asia for decades. Many IDMs such as Renesas, Infineon, Texas Instruments, and STMicroelectronics built global footprints long before supply chain resilience became a policy priority.
What Changed After 2020
The pandemic-era shortages permanently altered how risk is perceived and priced. Semiconductor supply proved difficult to substitute, and single-region dependency became a board-level concern. Redundancy is now something customers expect and are willing to pay for.
At the same time, industrial policy crossed a threshold. Incentives in the United States, Europe, and Japan became large enough to influence capital decisions. These programs do not override economics, but they reduce the cost penalty of building in higher-cost regions.
Customers and Packaging Began Pulling Fabs Closer
Equally important, customers began pulling manufacturing closer. Hyperscalers, automotive OEMs, and advanced system builders increasingly want tighter coupling between silicon, packaging, and systems.
Advanced packaging is now a major driver of performance, power efficiency, and cost. That favors regional clusters where fabs, OSATs, substrate suppliers, and system integrators can work in close coordination. It does not support a single global hub, but it also does not support full dispersion.
Why Foundries and IDMs Behave Differently
Foundries face hard constraints at advanced nodes. Yield learning depends on dense ecosystems of talent, suppliers, equipment support, and research institutions. These feedback loops take decades to build and cannot be recreated quickly. As a result, overseas foundry fabs are additive, not substitutive. They typically trail the leading edge and rely heavily on the core ecosystem.
IDMs have more flexibility. Because they control design and manufacturing and focus on longer-lived products at mature nodes, they can place capacity closer to customers without undermining competitiveness. For automotive and industrial markets, regional presence often matters more than absolute node leadership.
This is Controlled Diffusion, not Deglobalization
This expansion is not deglobalization, and it is not the hollowing out of Taiwan or other core ecosystems. It is controlled diffusion. Capacity is spreading, risk is being hedged, and resilience is being engineered while learning cores remain intact.
Will This Trend Stop
This trend is unlikely to reverse soon. As long as geopolitical uncertainty remains elevated, AI and electrification drive demand, and governments view semiconductors as strategic infrastructure, companies will continue adjusting their geographic portfolios. They will move chess pieces, not abandon the board.
The Bottom Line
The semiconductor industry is not running from its past. It is adapting by balancing what must remain concentrated with what can be responsibly replicated. Understanding that balance is key to understanding where the industry is headed.
