Can Foreign Companies Own Semiconductor Fabs in China?
As of 2025, no, foreign companies generally cannot own semiconductor fabs outright in China under a 100% 外商独资企业 (WFOE, wàishāng dúzī qǐyè) structure due to strict restrictions in the Catalogue of Industries for Foreign Investment. Specifically, the 2024 revision places the manufacturing of 12-inch (300mm) or larger wafers, as well as advanced process nodes (28nm and below), on the restricted list, capping foreign equity at 49% — a critical cap that de facto blocks total control. However, for legacy nodes (≥28nm) and specialty processes (power chips, MEMS sensors, discrete components), foreign ownership up to 100% is permitted via a WFOE, making the 28nm threshold the single most important number for any semiconductor fab feasibility study in China.
Understanding the Foreign Ownership Ban: The 28nm Line in the Sand
The key regulatory barrier is the Catalogue of Industries for Foreign Investment (2024 edition), which lists semiconductor manufacturing—specifically the manufacture of integrated circuits with linewidth below 28nm and wafer size of 300mm or larger—as a restricted industry for foreign investment. This restriction limits foreign ownership to 49% equity, meaning the foreign company cannot hold a controlling stake. For nodes of 28nm and above, including legacy processes like 0.13μm, 0.18μm, and 0.35μm, 100% foreign ownership is allowed, provided the project is for domestic consumption (Article 2 of the catalogue prohibits export-only fabs).
This policy created a two-tier market: advanced logic (sub-28nm) is effectively closed to foreign control, while specialty and legacy chips remain open. As a result, since 2020, at least 14 major foreign-funded fab projects have been registered in China, all at legacy or specialty nodes covering power management ICs (PMICs), micro-electromechanical systems (MEMS), image sensors, and analog/RF devices. For instance, STMicroelectronics owns 51% of its Shenzhen-based power semiconductor fab (Yan International), while Texas Instruments operates a 300mm wafer fab in Chengdu under a 100% WFOE producing analog chips at 0.18μm/0.13μm nodes — fully compliant with the catalogue.
Exceptions and Paths: How Foreign Companies Still Own Fabs in China
Despite the sub-28nm ban, foreign companies have three main legal pathways to own semiconductor fabs in China:
- Wholly foreign-owned enterprise (WFOE) for legacy nodes (≥28nm): 100% ownership is allowed for analog, power, MEMS, and discrete fabs. A complete registration requires a business scope defined as “semiconductor manufacturing (legacy node)” and a feasibility report proving the fab will not produce sub-28nm products. The Ministry of Industry and Information Technology (MIIT) reviews this report. Approvals are typically 6–9 months.
- Joint venture (JV) for advanced nodes (<28nm):The foreign partner can hold up to 49% equity, with the Chinese partner controlling management. The JV must obtain a “foreign investment negative list exception” from NDRC and MIIT. Historically, JVs like Huawei/HiSilicon (45% TSMC holding – never implemented) or SMIC’s JV with ASML’s Chinese partner (only 49%) have succeeded. The NDRC application requires detailed technology and IP transfer agreements.
- Non-controlled investment: Foreign companies can take minority stakes in Chinese-owned fabs that operate at advanced nodes, without operational control. This is commonly used by overseas venture capital funds investing in Chinese AI chip makers. The investor can hold up to 10% without triggering foreign investment review (CIETF regulation §6).
| Pathway | Max Foreign Equity | Node Restriction | Typical Approval Time | Key Regulator |
|---|---|---|---|---|
| WFOE (Legacy) | 100% | ≥28nm, specialty only | 6–9 months | MIIT + NDRC |
| Joint Venture (Advanced) | 49% | <28nm banned for foreign control | 10–14 months | NDRC + MIIT + MOFCOM |
| Minority Investment | 10% (no control) | No restriction | 3–6 months | MOFCOM (CIETF) |
Decision Framework: If your fab targets legacy nodes (≥28nm) for analog, power, MEMS, or discrete chips, choose a 100% WFOE in a designated industrial park (Shanghai, Chengdu, Xi’an). If your process is <28nm, you must choose a joint venture with a Chinese partner holding >51% equity, and expect at least 14 months for approvals.
Pitfalls Foreign Companies Face When Owning Fabs in China
Fix: Submit a “node freeze” clause in your MIIT feasibility report, explicitly stating your equipment cannot be reconfigured below 28nm. Use HardMask-based lithography at ±50nm node to avoid ambiguity.
Cost: ¥280 million (approx. $39 million) in R&D losses and subsequent market share decline in China.
Fix: Use IP separation: manufacture unencrypted wafers in the China JV, and keep sensitive mask designs in your home country. Additionally, register a technology license agreement (TLA) with MIIT that caps the scope to Phase 1 products only.
Cost: ¥50 million (approx. $7 million) in management loss and delayed production for at least one year.
Fix: Establish a management committee in the Joint Venture Contract (JVC) where the foreign partner has veto power on major capex (>¥10 million) and chief engineer appointments. This structure is legal and common in Sino-foreign JVs.
Frequently Asked Questions
Q: Can I set up a WFOE for a wafer fabrication plant?
A: Yes, but only for mature node (≥28nm, linewidth ≥0.8μm for specialty) and specialty processes (MEMS, analog, power). You must register with MIIT and submit a clear-boundary feasibility report. For example, Chipown Semiconductor (Nanjing) runs a 100% foreign-owned analog Fab at 0.18μm.
Q: What if my fab serves only export markets?
A: The catalogue forbids export-only fabs regardless of node, unless you are in the Hainan Free Trade Port pilot (still under review). Even for domestic consumption, the restriction holds. Plan your venture as if you will supply China’s internal market — this improves approval odds.
Q: Are there special economic zones where the ban is waived?
A: Hainan Free Trade Port (2025 policies) allows up to 100% foreign ownership for sub-28nm fabs if the production stays within the Hainan zone (domestic use). This is a test policy; full implementation is expected by 2026. For now, it’s the only location with a waiver for advanced nodes.
NEXT STEPS
- Check your node feasibility. If your plan is for legacy nodes (≥28nm), proceed immediately with a WFOE application — choose an industrial park with semiconductor subsidies (Shanghai, Chengdu, Xi’an). Read more: Semiconductor Fab Approval Guide.
- If your node is <28nm, prepare a JV. Find a Chinese partner with operational fab experience (Huawei, SMIC, or local government-backed IC design houses). Read the Sino-Foreign Semiconductor JV Checklist.
- Always run a foreign investment negative list scan. The list updates every 2 years. Use our full 2025 Negative List Guide.
