Win Semiconductors diligence pack

What they do

• World's largest GaAs RF foundry.
• Primary segment: Foundry / Pure-Play Foundry.
• Key products in the dataset: GaAs pHEMT foundry wafers for RF power amplifiers, InGaP HBT foundry wafers for PA modules, GaN-on-SiC wafers for high-power RF, Foundry PDK and design-kit services, 6-inch and 4-inch compound-semiconductor foundry.
• Market position in that segment: leader.

Role in the chain

• Win Semiconductors is a market leader in Foundry (Pure-Play Foundry), headquartered in Taiwan. World's largest GaAs RF foundry.
• 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: 2. Tracked customers: 9.
• Named suppliers (first 2): AIXTRON, Plasma-Therm.
• Named customers (first 8): Broadcom, MediaTek, NVIDIA, Qualcomm, AMD, Apple, MACOM Technology, Qorvo.
• 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

• Win Semiconductors itself is a leader in its primary segment.
• 1 of the tracked suppliers are a monopoly or leader: AIXTRON.
• 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 TWO:3105. The company is unpriced in this dataset — do not treat a missing cap as zero.
• 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 2 tracked suppliers for Win Semiconductors. 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: 1 of Win Semiconductors's tracked suppliers are a monopoly or leader (including AIXTRON). Which of those are actually single-source for the process step you care about?
• Ask: The dataset names 9 tracked customers for Win Semiconductors. How concentrated is demand among those names, and which of them have a documented second source in this graph?
• Ask: Win Semiconductors is positioned as a leader in Foundry. How replaceable is this vendor on the process step you are buying?
• Ask: Win Semiconductors 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?
