FD-SOI Chips See Demand Surge as China Builds Domestic Supply Chain
The fully depleted silicon-on-insulator (FD-SOI) market is expanding rapidly, fuelled by AI integration into physical devices. China is developing a full domestic supply chain, with YMTC's capital arm reportedly investing in 12-inch SOI technology.
FD-SOI Demand Rises with AI Integration
The market for fully depleted silicon-on-insulator (FD-SOI) chips is experiencing significant growth. This expansion stems from the increasing adoption of artificial intelligence (AI) in physical applications beyond traditional data centres. Devices such as vehicles, robotics, wearable technology, and various connected devices are now integrating AI functionalities.
Industry analysis, as presented at the 2026 Shanghai FD-SOI Forum, indicates this shift is widening the addressable market for FD-SOI technology, which offers advantages in power efficiency and performance crucial for edge AI computing.
China Pushes Domestic Supply Chain
In parallel with this market expansion, China is strategically constructing a comprehensive domestic supply chain for FD-SOI chips. This initiative spans critical components of semiconductor manufacturing, from the foundational substrates to advanced foundry capacity and sophisticated chip design capabilities.
Beijing's drive aims to reduce reliance on foreign technology and establish self-sufficiency in this key semiconductor segment. This domestic push is expected to reshape regional supply dynamics for FD-SOI components.
YMTC Capital Arm Enters FD-SOI
Further illustrating China’s commitment, YMTC’s capital arm is reportedly moving into the FD-SOI sector. This move aligns with China's broader objective to advance 12-inch silicon-on-insulator (SOI) technology. YMTC, a prominent Chinese memory chip manufacturer, is using its investment arm to support the development and production of these specialised wafers.
This involvement signals a concerted effort to build out domestic capabilities across the entire FD-SOI value chain, from materials to finished chips.
China's aggressive push into domestic FD-SOI production could significantly alter the competitive landscape for other Asian semiconductor manufacturers. Companies in South Korea, Taiwan, and Japan, currently leading in various chip segments, may face new competition in the FD-SOI market, particularly for automotive and IoT applications.
This development could prompt shifts in investment strategies and research and development focus across the region, as firms seek to maintain market share or identify niche opportunities within the evolving FD-SOI supply chain. The pace of China's capacity build-out will be a key metric to observe.
