Taiwan Semiconductor Manufacturing Company Explores Rare-Earth-Free Motors to Protect Advanced Chip Production

Highlights

• TSMC is investigating rare-earth-free motor alternatives for fab equipment after Chinese export control risks emerged through supplier inquiries.
• Induction, switched-reluctance, and ferrite-based motors are candidates, but semiconductor qualification can take months or years to complete.
• Taiwan's ITRI is developing a domestic rare-earth pilot line targeting 50% demand coverage within three years, though this remains unproven capacity.
• China's integrated magnet supply chain gives it leverage over equipment maintenance and replacement parts, even when chip fabrication occurs outside China.
• TSMC has not disclosed replacement contracts, qualification results, or deployment schedules, signaling supply-chain insurance rather than a technology breakthrough.
