Chinese chip foundry United Nova bets US$3B on AI power, optical interconnects

United Nova’s $3B bet isn’t just about AI power and optical interconnects—it’s a strategic repositioning to capture the undervalued potential of mature-node analog integration. Technically, this accelerates co-design capabilities between GaN/SiC power devices and silicon photonics in China, pressuring domestic equipment makers to deliver sub-45nm BCD platforms. Downstream AI server OEMs could reduce reliance on U.S.-based PMICs. Yet under tightening U.S. BIS controls on advanced packaging and EDA tools, compliance costs may surge over 30% if foreign IP or metrology tools are involved. TSMC and Samsung might counter with aggressive pricing to stall customer adoption, but if UNT successfully integrates chiplet-level power delivery with optical I/O, it could redefine AI chip energy-efficiency benchmarks. Within 18 months, China’s AI hardware stack is likely to undergo structural decoupling from U.S.-centric mid-layer components.
