A venture capital fund backed by Yangtze Memory Technologies Corp (YMTC), China’s leading producer of NAND flash memory, has officially invested in the domestic semiconductor firm SOI Micro. This move marks a strategic effort by the Chinese tech sector to diversify its chipmaking capabilities amid ongoing global supply chain challenges.

SOI Micro specializes in fully depleted silicon-on-insulator (FD-SOI) technology. This specific manufacturing process is designed to create low-power chips, which industry experts view as a complementary alternative to the traditional FinFET technology used by major global foundries. By backing a company focused on FD-SOI, the YMTC-linked fund is signaling a commitment to building a more resilient, domestic semiconductor ecosystem that is less reliant on mainstream, high-cost manufacturing routes.

The investment is led by prominent figures within the Chinese semiconductor industry, reflecting a broader national push to achieve greater technological self-sufficiency. While the specific financial terms of the deal were not disclosed, the involvement of YMTC—a company that has faced significant international scrutiny and trade restrictions—highlights the importance of this investment for China's long-term industrial strategy. The partnership is expected to accelerate the research and development of FD-SOI chips, potentially allowing Chinese manufacturers to bypass certain limitations imposed by current global export controls on advanced lithography equipment.
