How Samsung Maintained Semiconductor Leadership in China: Case Study

Samsung Electronics stands as the most successful foreign semiconductor company in China — a position it has held consistently for over two decades. While most multinational semiconductor firms have struggled with China’s evolving regulatory landscape, trade barriers, and the intensifying US-China technology decoupling, Samsung has not only maintained but deepened its semiconductor presence in China. The company operates two massive NAND flash fabrication facilities in Xi’an (Phase I and Phase II) representing over $25 billion in cumulative investment, a semiconductor assembly and test (SAT) facility in Suzhou, and a semiconductor R&D center in Shanghai. In 2025, Samsung’s two Xi’an fabs accounted for approximately 42.5 percent of the company’s total NAND flash production and an estimated 15.3 percent of worldwide NAND supply, according to the Semiconductor Industry Association (SIA). This case study examines the strategic decisions, operational approaches, and political navigation that have allowed Samsung to maintain its semiconductor leadership in China through the turbulent period of 2020-2026.

Background: Samsung’s China Semiconductor Strategy

Samsung’s semiconductor engagement with China dates to the early 1990s, but the game-changing decision came in 2012, when Samsung committed to building its first overseas NAND flash fabrication facility in Xi’an, Shaanxi Province. Xi’an offered a unique combination of incentives: a dedicated industrial park with subsidized utilities (critical for semiconductor fabs, where electricity costs represent 15-25 percent of operating expenses), a provincial government willing to co-invest and provide tax holidays, and a location far from China’s coastal security concerns but well-connected by rail and air to global logistics hubs. The initial Phase I investment of $7 billion in 2012 was Samsung’s largest overseas manufacturing investment at the time.

The strategic rationale was clear: locate manufacturing capacity within the world’s largest semiconductor-consuming market, avoid import tariffs, and build the political goodwill that would protect Samsung’s position during regulatory reviews. Over the following decade, Samsung expanded the Xi’an campus with Phase II (2017, additional $8 billion) and a second fab at the same site (2020, $10 billion), creating a NAND flash production complex capable of over 250,000 wafer starts per month. By 2025, employment at the Xi’an campus exceeded 8,000, making it one of the largest semiconductor manufacturing operations in China entirely owned by a foreign company.

Samsung’s diversification across memory types also protected its China position: Xi’an focuses on 3D NAND flash (from 64-layer through 238-layer and beyond), while Samsung also operates an assembly and test facility in Suzhou supporting both memory and logic products, and a 28nm CMOS image sensor production line in Shanghai’s Songjiang district. This geographic and product diversification created multiple pillars of China engagement, each with its own regulatory relationships and local partnerships.

China’s Memory Semiconductor Regulatory Framework and Samsung’s Navigation Strategy

China’s regulatory stance on foreign-owned memory semiconductor manufacturing has evolved significantly between 2012 and 2026. Samsung had to navigate multiple regulatory regimes:

The critical regulatory insight: China’s semiconductor regulations distinguish between logic chips (seen as strategically sensitive, subject to strict technology controls) and memory chips (seen as a commodity where capacity and price matter more than node advancement). Samsung’s focus on NAND flash — a technology where Samsung’s global leadership ($15 billion in 2025 NAND revenue, 34.5 percent market share) gives it pricing power and scale advantages — positioned it in a regulatory category that faced less scrutiny than logic fabs like SMIC. China needed Samsung’s NAND capacity to supply its domestic server, smartphone, and automotive industries; imposing restrictive conditions on Samsung would have disrupted China’s own electronics supply chain.

Navigating US-China Decoupling: Samsung’s Dual-Supply Strategy

Perhaps Samsung’s most impressive strategic achievement was maintaining operational continuity at Xi’an through the 2020-2025 period of escalating US-China technology conflict, while simultaneously investing in expanded NAND capacity in South Korea (Pyeongtaek campus) for geopolitical hedging.

The semiconductor equipment dilemma. US export controls implemented in October 2022 and tightened through 2024 restricted the supply of advanced semiconductor manufacturing equipment to China-based fabrication facilities. For Samsung Xi’an — which operates at NAND process nodes as advanced as 238-layer V-NAND — the question was whether EUV lithography tools (used for critical layers in V-NAND production) and advanced deposition/etch equipment would require US government licenses. Samsung successfully argued that its Xi’an operations were an extension of its global, Korea-headquartered manufacturing network, not a Chinese entity seeking to develop indigenous advanced chip production. The US BIS accepted this framing for most equipment categories, exempting Samsung Xi’an from the “presumption of denial” that applied to SMIC and other PRC-headquartered fabs.

Equipment supply chain bifurcation. Samsung implemented a careful “dual-sourcing” strategy for the Xi’an fab’s most sensitive equipment. For each process step, where possible, Samsung procured both US/Japanese equipment for general-purpose steps and Korean equipment (Samsung-owned subsidiary SEMES or Korean suppliers such as Wonik IPS) for the most export-controlled steps. This redundancy meant that if a specific US license was delayed or denied, Samsung could reconfigure a process module using alternative equipment without halting the entire production line. The strategy added approximately 8-12 percent to equipment CAPEX but insured against the multi-billion-dollar risk of a complete production stoppage.

Technology transfer management. Under the terms of its Phase I and Phase II investment approvals, Samsung committed to transferring certain NAND manufacturing process technology to local Chinese engineers. The company structured this transfer carefully: Chinese engineers at Xi’an learned specific process modules (deposition, planarization, metrology) but not the full integration recipes or advanced V-NAND architecture designs. The most sensitive process know-how remained at Samsung’s Giheung and Hwaseong facilities in Korea. This compartmentalized approach met China’s technology transfer expectations while protecting Samsung’s core intellectual property.

Captive consumption and export qualification. A significant portion of Xi’an’s NAND output serves Samsung’s own downstream products — its Galaxy-branded smartphones, tablets, PCs, and data center SSDs. This “captive consumption” model gives Samsung flexibility: during periods of geopolitical tension, Xi’an output can be shifted to internal consumption rather than open-market sales, reducing exposure to Chinese regulatory scrutiny over chip exports while keeping the fab running at high utilization.

Key Challenges and Mitigation

Rising Chinese domestic competition. Chinese NAND flash manufacturers — primarily YMTC (Yangtze Memory Technologies Co.), which has received over $30 billion in combined state investment — have advanced rapidly. YMTC’s 232-layer 3D NAND, introduced in 2023, directly competes with Samsung’s mainstream V-NAND products. Samsung countered with aggressive pricing in the Chinese market (discounting Xi’an-produced NAND by 10-15 percent versus global prices), rapid iteration to 286-layer and 300+ layer architectures, and exclusive supply agreements with China’s largest smartphone OEMs.

Labor cost escalation and talent retention. Xi’an’s semiconductor labor market tightened significantly between 2020 and 2025 as YMTC (based in Wuhan) and other Chinese memory startups competed for experienced process engineers. Samsung Xi’an’s average process engineer salary rose from approximately RMB 250,000 in 2020 to RMB 380,000 in 2025. Samsung mitigated this through non-salary benefits: subsidized housing in Xi’an’s Chip Town development, a technical ladder promotion system that offered Chinese engineers a career path to senior staff and principal engineer levels without requiring relocation to Korea, and a structured “learning sabbatical” program sending top performers to Samsung’s Korea fabs for 6-12 months of advanced process rotation.

Environmental and energy constraints. Xi’an’s inland location, while politically advantageous, creates operational challenges. Water scarcity in Shaanxi Province periodically threatens fab operations (semiconductor fabs consume 4-5 million gallons of ultrapure water daily). Samsung invested $200 million in a dedicated water recycling facility at the Xi’an campus, achieving 85 percent water reuse — one of the highest rates in the global semiconductor industry. For electricity supply, Samsung negotiated a direct power purchase agreement (PPA) with Shaanxi’s provincial grid and invested in on-site backup power generation, ensuring the fab’s Tier-4 (sub-10-minute) power reliability requirement was met despite the inland grid’s variable stability.

Tariff and trade diversification risk. The US maintains 25 percent tariffs on Chinese-manufactured electronics, including NAND chips. Samsung Xi’an’s output destined for US customers incurs these tariffs, increasing costs versus Samsung’s Korean fabs that ship tariff-free to the US under the US-Korea Free Trade Agreement. Samsung manages this by regionalizing Xi’an’s output: approximately 60 percent of Xi’an production serves the China domestic market, 25 percent goes to Asia-Pacific (excluding Korea), and only 15 percent enters the US market. Korean fabs serve the US and European markets preferentially.

Lessons for Foreign Investors

1. Memory semiconductors face a different regulatory category than logic. China treats NAND and DRAM fabs as capacity-oriented investments, not strategic-technology transfers. Foreign companies in memory manufacturing face less restrictive conditions than logic fabs, both from China’s regulators and from US export controls. This regulatory asymmetry should inform site selection for semiconductor investments in China.
2. Local government partnerships are as important as central government approvals. Samsung’s deep relationship with the Shaanxi provincial government and Xi’an municipal authorities — built over 14 years through job creation, tax revenue, and infrastructure investment — created a powerful local constituency that advocated for Samsung during central-government regulatory reviews. Foreign investors should prioritize provincial-level partnerships over Beijing-focused lobbying.
3. Dual-supply redundancy is essential for geopolitical resilience. Samsung’s investment in Korean backup capacity parallel to its Xi’an operations allowed it to maintain customer commitments during periods of equipment licensing delays. This “China + Korea” model is expensive but has proven indispensable for supply continuity.
4. Technology transfer can be compartmentalized without sacrificing investment approval. Samsung demonstrated that process module training (deposition, etching, metrology) satisfies China’s technology transfer requirements without revealing proprietary integration recipes. Foreign semiconductor manufacturers can meet regulatory expectations while maintaining core IP protection through modular knowledge transfer.
5. Environmental infrastructure investment is a competitive moat. Samsung’s $200 million water recycling plant and dedicated grid connection created operational advantages that smaller competitors cannot easily replicate. For any large-scale manufacturing investment in inland China, planning for environmental infrastructure carries a CAPEX premium of 5-8 percent but provides an enduring competitive advantage in operational reliability.

Where to Go From Here

Samsung’s sustained semiconductor leadership in China demonstrates that foreign companies can operate large-scale chip fabrication facilities successfully — but only with a multi-decade commitment, deep local partnerships, and a carefully managed geopolitical hedging strategy.
