Yangtze Memory Technologies Plans Major Expansion as U.S.–China Tech Tensions Intensify

Yangtze Memory Technologies (YMTC), China’s leading producer of NAND flash memory chips, is preparing to significantly expand its manufacturing footprint with plans to build two additional semiconductor fabrication plants, according to sources familiar with the matter.

The expansion would come on top of a third facility nearing completion, and together the three new plants are expected to more than double YMTC’s production capacity once fully operational.

Scaling Domestic Chip Production

Each of the planned facilities is designed to produce up to 100,000 wafers per month at full capacity. YMTC currently operates two fabs with a combined output of approximately 200,000 wafers per month, meaning the expansion could represent a major increase in China’s domestic semiconductor manufacturing capabilities.

The third factory, located in Wuhan alongside YMTC’s existing facilities, is expected to begin operations later this year. Initial production capacity is projected at 50,000 wafers per month by 2027, with further scaling anticipated over time.

Strategic Push for Self-Reliance

The expansion aligns with China’s broader effort to reduce dependence on foreign semiconductor technologies. The sector has become a focal point of geopolitical tension, with the United States imposing export restrictions aimed at limiting China’s access to advanced chipmaking equipment.

Recent proposals from U.S. lawmakers to tighten these controls further underscore the strategic importance of semiconductors in global technology competition.

Increasing Reliance on Domestic Suppliers

In response to these restrictions, YMTC has been strengthening ties with domestic equipment providers. More than half of the machinery being installed at the new Wuhan facility is reportedly sourced from Chinese companies, including Advanced Micro-Fabrication Equipment.

This includes critical tools used for advanced processes such as vertical stacking of chip layers—a key technology in NAND flash production.

YMTC has accelerated collaboration with local suppliers since being added to the U.S. Commerce Department’s Entity List in 2022, which limits its ability to procure certain foreign technologies.

A High-Stakes Expansion

The company’s expansion plans highlight the growing urgency within China to build a more self-sufficient semiconductor ecosystem. By increasing capacity and localizing supply chains, YMTC is positioning itself to navigate ongoing trade restrictions while supporting domestic demand for memory chips used in smartphones, computers, and other devices.

Industry and Geopolitical Implications

The move comes at a time when global semiconductor supply chains are being reshaped by geopolitical pressures. YMTC’s efforts to scale production and deepen domestic partnerships reflect a broader trend of regionalization in the chip industry.

While the company has not publicly commented on the plans, the reported expansion signals a long-term commitment to growth despite external constraints.

As competition between the U.S. and China continues to intensify, developments like YMTC’s factory expansion are likely to play a critical role in shaping the future of the global semiconductor market.
