TSMC Considers Producing 4nm AI Chips At Kumamoto Plant
Taiwan Semiconductor Manufacturing Co. is considering producing 4-nanometer semiconductors for artificial intelligence at its Kumamoto, Japan, plant, industry sources said on Dec. 12. TSMC operates the site through JASM, a joint venture with Sony, Denso and Toyota, and the plan could repurpose intended 6nm–40nm capacity and delay the second plant's 2027 start. The shift aims to strengthen Japan's domestic AI-chip supply amid global competition.
Key Points
- 1Consider introducing 4nm manufacturing tools at Kumamoto JASM facility, shifting from current 12–28nm production
- 2Responds to rising demand for AI semiconductors and intensifying global competition for advanced chip supply
- 3Anticipate delays to JASM Plant 2 start, requiring firms to revise capacity and supply plans
Scoring Rationale
Strategically significant for AI-chip supply, but reporting relies on industry sources and plans could change before formal confirmation.
