US chip fab map
Every US semiconductor manufacturing project we track: wafer fabs, packaging lines, and the materials and equipment plants that supply them. Each one carries its status, investment, federal award, and a link to the source behind every figure.
124 projects at 113 sites in 26 states. 55 are tied to a CHIPS Act award or preliminary terms, and 535 source links back the numbers.

How to read this
- A status is only as current as its "as of" date, which is the date of the source that supports it.
- Investment and jobs are the figures a company or agency announced. "Not stated" means no source gives a number for that site, not zero.
- "Shared" under CHIPS award means the award covers several sites and no per-site split is published.
- Company-wide totals are never assigned to a single site.
