SMIC Founder: 3nm/2nm Not Chip Success Key
💡SMIC says skip 3nm race—target niches for AI chips now
⚡ 30-Second TL;DR
What Changed
Zhang Rujing deems 3nm/2nm requirement a misunderstanding
Why It Matters
Encourages AI hardware firms to explore mid-tier nodes and niches, potentially lowering costs amid US-China tensions. Diversification could stabilize supply for AI accelerators.
What To Do Next
Assess mid-node foundries like SMIC for cost-effective AI chip prototyping.

- •SMIC, China's top chipmaker, advocates segmented strategy
🧠 Deep Insight
AI-generated analysis for this event.
🔑 Enhanced Key Takeaways
- •Zhang Rujing emphasizes that the global semiconductor market is dominated by mature nodes (28nm and above), which account for the vast majority of chip demand in automotive, industrial, and IoT applications.
- •The strategy advocates for 'specialty process' technologies—such as power management ICs, RF, and sensors—where performance is defined by analog characteristics rather than transistor density.
- •This perspective aligns with China's broader 'dual circulation' strategy, aiming to achieve self-sufficiency in legacy and mature node production to mitigate the impact of international export controls on advanced lithography equipment.
🔮 Future ImplicationsAI analysis grounded in cited sources
SMIC will prioritize capacity expansion in 28nm and 40nm nodes over aggressive 2nm R&D.
Focusing on mature nodes aligns with the founder's stated strategy of targeting high-volume, cost-sensitive niche markets rather than competing in the high-cost, low-yield advanced node race.
Chinese domestic chip demand will increasingly decouple from global leading-edge node requirements.
By emphasizing specialty processes, the industry is signaling a shift toward optimizing existing infrastructure for local industrial needs rather than chasing the Moore's Law scaling limits set by TSMC and Samsung.
