Coverage & methods

What the evidence can establish.

Coverage is assessed against named research questions, not a claim to cover the entire industry. This first collection prioritizes specific, traceable claims over broad counts.

partially covered

AI accelerators

Covered

  • NVIDIA A100 and H100 product/die/architecture distinctions
  • Blackwell 2024 process description

  • Dated Blackwell wafer manufacturing at a named TSMC Phoenix site

Still missing

  • MI300 die-specific foundry proof
  • Exact die/SKU-to-fab-phase assignments
  • Shipment volumes and customer allocation
partially covered

HBM supply chain

Covered

  • HBM generation used by specific accelerator configurations
  • SK hynix and Micron dated HBM3E production announcements

Still missing

  • Direct supplier-to-accelerator contracts
  • HBM production fab assignments
  • Supplier shares and allocation history
partially covered

Foundries and fabs

Covered

  • TSMC Arizona first-fab N4 capability
  • Second-fab planned N3 capability kept separate
  • Samsung foundry selection for planned Tenstorrent chiplets
  • Blackwell wafer production at the TSMC Phoenix site, preserving separate 2025 and 2026 observations

Still missing

  • Exact Blackwell die, SKU, fab phase and process mapping
  • Actual installed equipment models

Still missing

  • Named shipped Tenstorrent SKU and foundry
  • Legal closing dates and current ownership percentages
  • Independent evidence beyond issuer statements
planned

Equipment and materials

Still missing

  • ASML–TSMC customer-support source was insufficient to establish the proposed supplier claim; the claim is retained as retracted
  • Fab-level equipment installations
  • Process-step and material dependencies
  • Alternative qualified suppliers
planned

Broader semiconductor industry

Still missing

  • Mobile SoCs and Apple modem history
  • EDA and IP design wins

Confidence and verification

The evidence index combines source authority (up to 45), primary-source status (15), independent corroboration (15), extraction certainty (10), and entity-resolution certainty (15). It is a transparent ranking rule, not a calibrated probability. Repeated reports from the same origin do not count as independent sources.

UNVERIFIED candidates remain separate. SUPPORTED claims meet the source policy. VERIFIED requires human review. Conflicting evidence produces DISPUTED; overdue review produces STALE; withdrawn interpretations are RETRACTED and remain in history.

Two separate clocks

Validity records when evidence supports a relationship. Knowledge time records when VLSI observed or reviewed it. Publication, retrieval and production-start dates are different fields. Unknown dates remain unknown; intervals use an exclusive end date.

Source hierarchy and rights

Tier A covers direct official documentation, filings, technical reports and government or standards sources. Tier B covers research and credible industry analysis. Tier C covers secondary media, and Tier D covers community or unverified material. Lower-tier evidence can be retained without being accepted. This seed stores concise factual summaries and references; it does not redistribute source documents.

Traversal acceptance ledger

Company → chip → foundry → process → fab → equipment

partial Product/die/process and fab capability evidence exist. Blackwell wafer production has site-level proof at TSMC Phoenix; exact die/SKU, fab phase, process and installed equipment remain unproven.

Company → chip → memory → memory supplier → fab

partial A shared memory generation is a technology association, never proof of a supply relationship. Product-specific supplier and fab evidence remain gaps.

Company → supplier → supplier dependency → country

partial NVIDIA reports using TSMC and Samsung wafer-foundry services at portfolio level. Facility locations are covered separately. No numerical exposure or SKU-specific allocation is established.

Company → competitor → competing product

partial AMD-reported corporate competitors and product designs are covered. Specific product competition needs segment/time evidence.

Company → investment → startup → product → foundry

partial Financing participation and planned chiplet/foundry selection are covered. This is not evidence of completed manufacture or continuing ownership.

Next research priorities

  1. Direct accelerator-to-HBM-vendor statements
  2. Exact Blackwell die/SKU, fab phase, process and periods beyond the sourced snapshots
  3. Fab equipment installation announcements
  4. Two independent sources for the highest-value claims
  5. Historical entity-name and acquisition event evidence
Planned capabilities
  • Production autonomous acquisition scheduler
  • PostgreSQL production system of record
  • Calibrated entity-resolution precision benchmark
  • Vector retrieval, GraphQL and MCP wrappers
