NVIDIA Vera Rubin uses CoWoS-R and CoWoS-L advanced packaging from TSMC, critical for multi-rack pod scale AI infrastructure
Jensen Huang· NVIDIA· AI· 2026-06-02· about TSMC (TSM)
“Three nanometer process, CoWoS-R and CoWoS-L packaging”
Why it matters
CoWoS is TSMC's most advanced and constrained packaging technology. Vera Rubin is now ramping into full production with multiple enterprise customers, making CoWoS availability a critical gating factor for AI infrastructure deployment.
Investment implication
TSMC will face sustained CoWoS capacity pressure from Vera Rubin deployments alongside existing demand from NVIDIA's datacenter GPUs. This may require capex acceleration in advanced packaging facilities, benefiting equipment suppliers.
