About our semiconductor coverage

Aterio tracks semiconductor manufacturing investment across the United States, fabs, packaging plants and the supplier facilities that follow them.

These notes cover where construction actually stands, how much power and water each site needs and what a fab does to the local labor and housing market. We follow announced capacity through permits, contractor activity and equipment move in, so you can tell the projects that are progressing from the ones that are still on paper.
