N2/A13/A14/1nm ramps & capex
Key Questions
What is the timeline for TSMC's N2 and A14 nodes?
N2 enters high-volume manufacturing in late 2025, with A14 targeted for 2028 and 1nm around 2030-31. These ramps include 12 new fabs and a $20B capex increase.
How does AMD's EPYC Venice relate to TSMC's 2nm process?
AMD's 6th Gen EPYC Venice has entered volume production on TSMC 2nm as the first HPC product on the node. Lisa Su's Taiwan visit and $10B+ investment confirm deep strategic ties.
What investments support TSMC's capacity expansion?
AMD plans over $10B in Taiwan's AI and semiconductor ecosystem, while TSMC boosts overall capex. This reinforces full 2nm booking through 2027.
How is TSMC addressing advanced packaging and new nodes?
TSMC is advancing CoWoS and introducing A13 alongside N2 ramps. Ecosystem partners like Siemens EDA are expanding AI and packaging collaborations.
What impact could supply chain issues have on TSMC's 2nm?
Capacity has become a 2026 bottleneck, with plans to expand through 2027. Supply chain constraints may affect 2nm ramps but are being mitigated via multiple fab builds.
Why is AMD extending 2nm across its roadmap?
AMD plans to use TSMC 2nm for follow-on products like Verano, targeting cloud, enterprise, and AI infrastructure. This deepens reliance on TSMC versus alternatives.
What is Lam Research's role in TSMC's AI efforts?
Lam Research is adding AI and sensing capabilities to chipmaking tools while eyeing US expansion. It supports TSMC's advanced node and packaging ramps.
How do TSMC's Japan fabs factor into the expansion?
TSMC's Japan unit turned profitable in Q1 with a second fab starting 3nm production in late 2027. A third fab is under construction to boost regional capacity.
N2 HVM late 2025; A14 2028; 1nm ~2030-31 +12 fabs; +$20B capex. AMD EPYC Venice volume production + Lisa Su Taiwan visit +$10B+ investment confirm full booking thru 2027 and strategic TSMC reliance. Bernstein confirms TSMC 2nm dominance over Intel/Samsung. Kumamoto Fab2 upgrading to 3nm faster than expected with subsidies.
