Direct answer

NVIDIA's supply chain spans semiconductor manufacturing, advanced packaging, memory, substrates, and systems integration, with key partners including TSMC (foundry), SK Hynix and Micron (HBM memory), Samsung (memory and packaging), Foxconn and Quanta (system assembly), and ASE Group (packaging). TSMC manufactures virtually all of NVIDIA's GPUs on 4nm and 5nm process nodes. CoWoS advanced packaging — also sourced from TSMC — is a critical bottleneck for H100 and H200 GPU production. NVIDIA's Blackwell architecture further deepens reliance on TSMC's cutting-edge nodes and CoWoS-L packaging. Supply chain constraints in 2023–2024 were primarily driven by limited CoWoS capacity, not chip fabrication alone.

Key Takeaways

  • TSMC is NVIDIA's sole foundry partner, manufacturing all high-end GPUs on advanced process nodes (4nm/5nm), making it the single most critical supply chain dependency
  • SK Hynix is the primary supplier of HBM3 and HBM3e memory stacked on H100/H200/B100 GPUs; Micron has qualified as a second HBM3e supplier for Blackwell
  • CoWoS (Chip-on-Wafer-on-Substrate) advanced packaging capacity at TSMC was the primary production bottleneck for AI GPUs in 2023–2024
  • Foxconn (Hon Hai), Quanta Computer, and Wistron serve as ODM/EMS partners assembling NVIDIA-based servers and HGX compute trays
  • ASE Group and Amkor Technology provide additional advanced packaging and assembly services for NVIDIA's broader product portfolio
  • Amphenol and TE Connectivity supply connectors and high-speed interconnects used in NVIDIA's DGX and HGX server platforms
  • Fabrinet and Coherent supply optical transceiver components critical to NVLink and InfiniBand networking in large GPU clusters
  • Substrate suppliers including Ibiden and Shinko Electric are critical for GPU package substrates, with limited global capacity creating additional supply constraints

Evidence & Analysis

  • TSMC's CoWoS capacity was reported by multiple analysts (including Morgan Stanley and TrendForce) as the binding constraint limiting H100 GPU shipments through most of 2023, not wafer starts
  • SK Hynix disclosed in 2023 earnings calls that NVIDIA accounts for a dominant share of its HBM3 output, with HBM3e qualification completed for H200 in late 2023
  • Micron announced HBM3e qualification with a major AI GPU customer (widely identified as NVIDIA) in Q1 2024, targeting Blackwell-generation products
  • NVIDIA's 10-K filings identify TSMC and Samsung as primary manufacturing partners, with concentration risk explicitly cited as a key supply chain risk factor
  • Ibiden and Shinko Electric (Japan) supply ABF substrates for GPU packages; Ibiden has publicly disclosed NVIDIA as a major customer driving capacity expansion investments
  • NVIDIA's NVLink Switch systems rely on optical components from suppliers including Coherent and II-VI (now Coherent), critical for 400G/800G interconnects in GPU clusters
