​It is the underbelly of an Intel factory. The roots giving life to the tree above. The sub fab is full of tens of thousands of pumps, transformers, power cabinets, scrubbers, treatment systems and more — all to support the 1,200 chipmaking tools in the clean rooms directly above.

Take a sneak peek into Intel Oregon’s D1X sub fab, a nearly 700,000-square-foot seldom-seen world where you’ll see extreme ultraviolet (EUV) support machines, air shaft zones and giant pipes large enough to fit a small car.

Intel’s factories are the culmination of years of innovation by Intel and its supply chain partners and are part of Intel’s efforts to advance its longstanding commitment to sustainability.
