After four years of construction, Intel said on Thursday that its Fab 52 semiconductor plant in Chandler, Arizona, is now turning out its first chips. The company also shared more details about the long-awaited CPUs that it will be producing in the facility using Intel’s brand-new 18A process technology. Late last month, Intel invited dozens of analysts and business partners, along with a handful of journalists, to tour Fab 52. During the tour, Intel executives emphasized that Fab 52 is the most advanced chip manufacturing plant in the world. In the early 2010s, for example, Intel made another significant node, or process advancement, when it introduced 32-nanometer chip technology.
