NVIDIA Locks In 2.5x Substrate and 4x Interposer Capacity With Six Suppliers
NVIDIA announced at GTC Berlin on October 21, 2026 a multi-process capacity expansion with six suppliers — Ibiden, Samsung Electro-Mechanics and Unimicron (package substrates), Amkor (interposer wafers), KYEC (test) and SPIL (CPO optical engines) — targeting a 2.5x increase in NVIDIA-dedicated substrate capacity over three years. Amkor's Korean interposer wafer capacity is targeted to rise more than 300% by end-2028, SPIL's optical engine output 15x by mid-2027 with a further doubling by end-2028, and NVIDIA's overall test capacity to double between 2026 and 2027, with Jensen Huang stating 'Demand is extraordinary. Capacity is the constraint.'
Advanced-packaging and substrate availability — not GPU die supply — has been the binding constraint on Rubin-class accelerator output, and these parallel commitments should begin easing ABF/FC-BGA and interposer lead times from 2027, though Ibiden's tranche only ramps in 2028. Baselines are undisclosed, so the multipliers cannot be compounded into unit supply; treat this as a directional lead-time and allocation signal rather than a cost reduction.
