Introduction
In a move that may reshape the compound semiconductor ecosystem, Taiwan Semiconductor Manufacturing Company (TSMC) has announced its plans to gradually exit the gallium nitride (GaN) foundry business by July 31, 2027.
The decision, first revealed through an SEC filing by U.S.-based power semiconductor firm Navitas Semiconductor, has triggered discussions across the industry about the future of GaN technologies and the competitive landscape.
Why TSMC is Exiting the GaN Business
According to the filing and subsequent industry reports, TSMC exit follows an internal review of its GaN wafer business.
The foundry giant stated that the exit aligns with its long-term strategic and financial roadmap, which prioritizes high-growth sectors like advanced logic, 3D packaging, and leading-edge nodes (e.g., 3nm and 2nm processes).
While GaN has demonstrated enormous potential in applications ranging from fast chargers and power electronics to RF communication and EVs, TSMC has chosen not to expand capacity or lower prices to compete aggressively in this niche segment.
Key factors behind the move include:
- Intense price competition from Chinese GaN foundries
- Low profit margins and limited economies of scale
- TSMC’s focus on high-value core businesses
- Strategic realignment in response to global market shifts
TSMC emphasized that it remains committed to supporting current customers through a carefully managed transition period until 2027, ensuring no disruption to ongoing supply chains.

Navitas on the Lookout: Powerchip (PSMC) in Focus
Navitas Semiconductor, a leading player in GaN ICs for power conversion, has already begun evaluating alternative foundry partners. According to the same SEC filing, Powerchip Semiconductor Manufacturing Corporation (PSMC)—a fellow Taiwanese foundry—is a top candidate to take over GaN capacity for Navitas.
PSMC has been expanding its specialty technology capabilities in recent years and could offer a smoother transition given its local presence, mature infrastructure, and growing portfolio in power semiconductors.

A Big Opportunity for India’s Semiconductor Ambitions
TSMC’s exit from the GaN foundry business presents a significant opportunity for India to step into the compound semiconductor manufacturing space.
With its growing focus on electronics self-reliance and robust government incentives under the Semicon India Program and Design-Linked Incentive (DLI) scheme, India can position itself as an alternative GaN hub in the Indo-Pacific region.
India’s Ministry of Electronics and IT (MeitY) has already approved multiple semiconductor proposals, and gallium nitride has been identified as a strategic technology for power electronics and defense applications.
Companies like Tata Electronics and Sahasra Semiconductors have signaled interest in specialty fabs, and GaN foundry services could offer high-value, high-margin differentiation for new entrants.
Here’s a quick snapshot comparing key regions in GaN manufacturing potential:
| Region | Current Status | Key Advantage | Growth Potential |
|---|---|---|---|
| China | High-volume, low-cost | Price competitiveness | Saturated |
| Taiwan | Mature foundries | Tech expertise, supply chain | Stabilizing |
| India | Emerging player | Government support, talent pool | High |
| U.S./Europe | Niche production | R&D strength, military demand | Moderate |
If India can leverage this transition period, it could attract fabless GaN companies looking to diversify away from China and Taiwan. With timely investments in GaN-specific fabs, packaging, and talent, India could evolve into a trusted GaN foundry destination by the end of the decade.
Industry Reactions: What This Means for the GaN Ecosystem
TSMC exit is being viewed as a strategic rather than technological decision. GaN technology itself is not in decline—in fact, it continues to gain adoption in several high-efficiency, high-frequency applications.
However, observers note that:
- TSMC was never a high-volume GaN player; its role was more focused on niche support.
- Price wars initiated by Chinese foundries—especially in consumer power markets—have eroded profitability.
- New specialized foundries in Asia, including China and Taiwan, are scaling up GaN at significantly lower cost.
- Fabless GaN players like Navitas will need to diversify their supply chains quickly.
- India and Southeast Asia may emerge as attractive destinations for GaN foundry expansion amid global diversification efforts.
Strategic Implications: A Pivot Point for GaN Supply Chains
While the GaN foundry landscape remains crowded with emerging contenders, TSMC’s departure may open new opportunities for India’s upcoming semiconductor foundries, especially under the country’s “Make in India” and design-linked incentive (DLI) schemes.
As advanced packaging and wide-bandgap semiconductors become increasingly vital for energy-efficient systems and EVs, countries investing in this space early stand to benefit.

Conclusion
TSMC planned to exit from the GaN business by 2027 marks a significant shift in the compound semiconductor supply chain. While it reflects a strategic realignment rather than a technology dismissal, it leaves a crucial gap that firms like Navitas and PSMC are now working to fill.
As demand for GaN continues to rise—especially in power electronics, AI servers, and electric mobility—the race is on for next-generation foundry partners who can deliver at scale, speed, and cost. And in this changing landscape, new regional players might just find their opening.
