Here’s why TSMC and Intel keep building foundries in the Arizona desert


Enlarge / In 2020, Intel partnered with the Nationwide Forest Basis in Section III of a venture changing invasive Arundo and Tamarix weed species with native flora and revegetating burned-off areas. This section of the venture goals to revive 79 million gallons of recent water per yr.

Two of the world’s main chip producers—Intel and TSMC—are growing their US-based manufacturing presence by building new vegetation in Arizona.

Chip foundries are critically depending on water, and Arizona is likely one of the driest states within the nation. Arizona will get solely 13.6 inches of annual rainfall (compared with 50-60 inches in a lot of the Deep South, or 30.3 inches average for the USA as an entire). However as Forrester analysis director Glenn O’Donnell instructed CNBC, chip-fabrication vegetation are just like indoor swimming swimming pools—”you want lots to fill it, however you do not have so as to add a lot to maintain it going.”

Counterintuitively, the famously thirsty trade may even enhance the native water provide on account of a concentrate on reclamation and purification—Intel has funded 15 water restoration tasks within the Grand Canyon State with a objective of restoring 937 million gallons per yr, and it expects to achieve net positive water use as soon as the tasks are accomplished.

What Arizona lacks in water, it makes up for with general stability—the state could be very seismically secure and doesn’t endure from hurricanes or wildfires, with low dangers of different pure disasters comparable to tornadoes as well. Constructing chip fabs with out such ensures is feasible—for instance, Intel has a big presence in Oregon—however chip fabricators on the West Coast should take excessive isolation measures, which Arizona vegetation do not require.

Arizona’s lack of rainfall comes with one other profit—plentiful sunshine, which former Arizona Gov. Janet Napolitano as soon as said provides the state the potential to be “the Persian Gulf of photo voltaic power.” As of 2018, the state’s utility firms generated roughly 5.2 GW—practically 5 % of its whole energy funds—through photo voltaic era. Distributed (nonutility-scale) era in Arizona supplied one other 2.3 GW in the identical yr.

The human issue, nevertheless, might add as much as greater than the state’s pure benefits do. Intel established its presence in Arizona greater than 40 years in the past and presently employs greater than 12,000 individuals within the state. Arizona native universities responded by establishing “a robust popularity for semiconductor design programs and analysis,” based on Gartner analyst Alan Priestley. And, as Forrester director O’Donnell factors out, “the political equipment in Arizona is decided to make the state enterprise pleasant… the current bulletins by Intel and TSMC come through lots of assist from federal, state, and native authorities entities.”
