Supplier directory

The semiconductor industry runs on a deep supplier base — tools, chemicals, wafers, materials, and dozens of support services. This is a map of those categories and the suppliers we can verify today.

Honest coverage

Categories with verified suppliers are shown first. The rest of the taxonomy is listed as Researching — the slots exist, but we don't invent vendors to fill them. 19 categories, 5 populated so far.
