TSMC Agrees to Produce Three 3Nm Chips for Xiaomi

Taiwan Semiconductor Manufacturing agreed to produce three custom chips for Xiaomi, including a next-generation three-nanometre smartphone processor starting in 2026.

The contract ties the $2.0 trillion Taiwanese foundry directly into the Chinese brand’s hardware expansion across flagship handsets, smart devices and automotive platforms. Xiaomi plans to deploy the primary 3nm design, designated the Xring O3, in its premium smartphones before rolling out two companion processors for consumer artificial intelligence devices and autonomous vehicle controls.

Expanding beyond data centres

Adding Xiaomi diversifies TSMC’s advanced-node order book at a time when top-tier 3nm wafer allocation has remained heavily concentrated among Western computing and mobile clients. Handset manufacturers in Asia have spent three years attempting to bring proprietary silicon in-house to reduce their dependence on merchant chipmakers. Xiaomi’s commitment to custom designs manufactured on TSMC’s cutting-edge lithography mirrors earlier silicon strategies from rival hardware makers, though extending those designs into vehicle autonomy widens the operational scope.

For consumer tech brands in Asia, controlling chip architecture allows tighter software integration across connected ecosystems, from living-room appliances to electric sedans. The arrangement secures advanced fabrication capacity for Xiaomi while providing TSMC with volume demand outside its core server and cloud computing base.

Wafer volume targets

Initial commercial success hinges on the manufacturing yield and delivery pace of the Xring O3 line during 2026. Market performance will depend on the speed at which Xiaomi ramps retail shipments of its 3nm handsets and incorporates the subsequent automotive silicon into its production vehicles.
