TSMC diligence pack

Operator note

Treat TSMC as a process-node and capacity decision, not a commodity foundry bid. The graph names a long supplier list and a short list of fabless customers. Replaceability is the question; this dataset does not carry a price or a revenue split for the relationship.

Editorial slot. It does not add a metric the dataset does not already carry.

What they do

• World's dominant foundry, manufacturing nearly all leading-edge chips.
• Primary segment: Foundry / Pure-Play Foundry.
• Key products in the dataset: N3/N2 processes, CoWoS packaging.
• Market position in that segment: leader.

Role in the chain

• TSMC is a market leader in Foundry (Pure-Play Foundry), headquartered in Taiwan. World's dominant foundry, manufacturing nearly all leading-edge chips.
• Ask: On the step you actually buy, is this company the process owner, a second source, or a distributor? The segment label is not a substitute for that answer.

Counterparties on the graph

• Tracked suppliers: 173. Tracked customers: 98.
• Named suppliers (first 8): Ajinomoto, ASML, Carl Zeiss SMT, Lasertec, TRUMPF, Advantest, Air Liquide, AIXTRON.
• Named customers (first 8): Analog Devices, ASPEED Technology, Broadcom, MediaTek, Nordic Semiconductor, Novatek Microelectronics, NVIDIA, OpenAI.
• Ask: Which of those edges are in a filing or a primary-source quote, and which are segment-inferred? Do not treat the two as the same fact.

Concentration and replaceability

Operator section

• TSMC itself is a leader in its primary segment.
• 45 of the tracked suppliers are a monopoly or leader: Ajinomoto, ASML, Carl Zeiss SMT, Lasertec, TRUMPF, Advantest.
• Ask: If the named monopoly or leader supplier stopped shipping, is there a qualified second source on that process step? If the dataset does not name one, do not assume one exists.

Geography and jurisdiction

• Headquarters country in the dataset: Taiwan.
• Ask: Where do the fabs, plants or logistics nodes actually sit, versus the HQ country on this record? This dataset records headquarters, not every site.

Public-markets facts (only what is on the record)

Investor section

• Public company, ticker NYSE:TSM. A live market cap is on the company profile; this pack does not restate it as a diligence conclusion.
• Ask: What does the latest reported period (if any) say about capacity, backlog and customer concentration? If the company page has no revenue figure, that number is not in this dataset.

Operator checklist

Operator section

• Ask: The dataset records 173 tracked suppliers for TSMC. Which of those edges are researched (named in a filing or primary source) versus segment-inferred, and what happens if one of them stops shipping?
• Ask: 45 of TSMC's tracked suppliers are a monopoly or leader (including Ajinomoto, ASML, Carl Zeiss SMT, Lasertec). Which of those are actually single-source for the process step you care about?
• Ask: The dataset names 98 tracked customers for TSMC. How concentrated is demand among those names, and which of them have a documented second source in this graph?
• Ask: TSMC is positioned as a leader in Foundry. How replaceable is this vendor on the process step you are buying?
• Ask: TSMC is headquartered in Taiwan. What jurisdiction, export-control or logistics risk sits at that HQ, versus at the fabs or plants the filings actually name?

Investor checklist

Investor section

• Ask: Is the graph position (monopoly / leader / major / challenger / niche) the thing you are underwriting, or a product line the one-liner does not cover?
• Ask: Which named customers in this graph could switch, and which named suppliers could not be replaced in a year? Count only names this dataset actually lists.
• Ask: What is not in this dataset — site-level capacity, contract terms, revenue split by customer — that you still need from a filing or a call?
