The European Semiconductor Atlas

I decided to do the atlas as a standing data product. It exists because the datasets Europe's chip debate runs on are either paywalled, stale, or assembled by the people selling a conclusion and because I needed the numbers myself and got carried away.

What the atlas contains today:

Wafer fabs 125 fabs across 99 campuses in the EU-27 plus the UK, Switzerland and Norway, from Intel Leixlip down to 20-person pilot lines. Every record carries process, status, capex and sources; since July 2026 also ultimate ownership (who actually controls each fab, down to jurisdiction), documented public subsidies (€15.4bn of approved aid, with Commission case numbers where they exist), and production capacity where — and only where — the operator has published a number. The interactive map is here.

Back-end: 44 sites. Assembly, test and packaging: the layer everyone forgets and Europe barely has. One large merchant OSAT on the entire continent. Zero operational interposer-class advanced-packaging production; one announced.

Equipment: 86 manufacturing and R&D sites. The machines Europe builds for the world's fabs, from Veldhoven's EUV monopoly to two RF-generator plants outside Warsaw — including the four sites nobody else on Earth can replace.

Every fact carries its source, per field, and a date stating when it was checked. Gaps stay visible: where a number is undisclosed, disputed or its source unreachable, the record says so instead of estimating. And the data is CC BY; the raw GeoJSON and CSV can be downloaded.

I plan to update the atlas quarterly. Each update should get a changelog post in this section: what was announced, what broke ground, what quietly died since the last snapshot.

If you find an error, or you operate one of these sites and your numbers are better than mine: write to kontakt@richard-stahl.at. Corrections get applied with attribution.
