Although GlobalFoundries’ chips are considered legacy nodes, the process and resources needed are still incredibly complex. Caulfield said each silicon wafer goes through at least 1,000 steps over 90 days in the Malta fab. The process requires extensive cleaning, cooling and chemical treatment, which uses a lot of water. GlobalFoundries says Fab 8 uses about 4 million gallons of water a day, reclaiming 65% of that.<\/p>\n

“Upstate New York is a very good place for access to high-quality and abundant water,” Caulfield said.<\/p>\n

All the heavy machinery also requires about 2 gigawatts of power per day, according to Hui Peng Koh, who heads up the Malta fab. She said it’s enough power to “run a small city.”<\/p>\n

“I would say our lowest-cost power is in the U.S.,” Caulfield said. “A lot of our power in upstate New York, where this facility is at, comes from hydroelectric, so it’s a greener power. In both Europe and Singapore, much of that power comes off of natural gas.”<\/p>\n

Then there’s the manpower. GlobalFoundries has 13,000 employees worldwide. About 1,500 people report to Koh in Malta. She told CNBC it’s “challenging to attract talent to this part of the world.”<\/p>\n
