Chinese state-owned company YMTC endeavors to evade American restrictions by constructing a production line utilizing indigenous technology - their objective being to seize a 15% share of the NAND market by the end of 2026.
In the rapidly evolving world of semiconductors, Yangtze Memory Technologies Co. (YMTC) is making strides in localising its fabrication tools for NAND flash memory production. The company is gearing up to pilot its first NAND production line fully built with domestic equipment in 2025, marking a significant step towards reducing reliance on foreign technology.
This move comes amidst U.S. restrictions imposed on YMTC since 2022, which have limited the company's access to technology. However, YMTC's determination is evident in its impressive production capacity. The Wuhan Phase 2 NAND production line has more than doubled its output, reaching 130,000 wafers in Q2 2025, compared to 60,000 wafers in the same period the previous year.
Technological advancements are also on the rise at YMTC. The company is improving its 3D NAND technology by increasing layer counts, currently at 270 layers. While this is below market leaders Samsung (286 layers) and SK hynix (321 layers), it is a significant step towards closing the gap.
YMTC's ambitions extend beyond China's borders, as the company aims to capture about 15% of the global NAND market share by 2026. This target aligns with China's broader ambitions to increase domestic chip manufacturing self-sufficiency under initiatives like "Made in China 2025." However, challenges such as supply chain constraints and global NAND oversupply impacting industry profitability remain.
As YMTC prepares for its trial production line using Chinese-made equipment, the company is also making investments in local tool and material suppliers to support its production network. The upcoming trial line is intended to test the capabilities of tools made in China, not to produce 3D NAND devices in high volume initially.
Despite the challenges, YMTC's progress in tool localization and capacity expansion is significant for China's semiconductor independence. However, the company must still overcome technological gaps and market headwinds to meet its 2026 market share goal.
| Aspect | Current Status (mid-2025) | |----------------------------------|---------------------------------------------------------| | Fabrication Tool Localization | First fully China-made NAND line set for pilot runs in 2025 | | Production Capacity | Wuhan Phase 2 NAND line producing 130,000 wafers in Q2 2025 | | Technology Development | 3D NAND with 270 layers, improving towards competitors’ level | | Market Share Goal | Targeting 15% global NAND share by 2026 | | Challenges | U.S. sanctions limit technology access; oversupply impacts market |
- YMTC's efforts in localizing its manufacturing tools for NAND flash memory production extend to investing in local suppliers for tools and materials, a move aimed at strengthening their production network.
- The increasing technological advancements at YMTC are evident in their 3D NAND technology, which currently boasts 270 layers, a significant step towards closing the gap with industry leaders such as Samsung and SK hynix.
- With the pilot of the first NAND production line fully built with domestic equipment scheduled for 2025, YMTC is poised to make strides in the finance and investing arena by reducing reliance on foreign technology, a key aspect of their broader business strategy that aligns with China's "Made in China 2025" initiative.
