Working at scales simultaneously vast and incomprehensively nanoscopic, a team of thousands of designers, contractors, and craft workers delivered Intel’s 2.9-million-sq-ft chip fabrication facility in less than four years. The $5-billion-plus Fab 52 project essentially establishes a new city within an existing city of factories built over decades on Intel’s expansive 600-acre Ocotillo campus in Chandler, Ariz., continually growing as chip technology evolves. “Getting a chance to build a leading-edge wafer fabrication facility, I find, is extremely challenging but also exciting, because the scale and breadth of the project is hard to understand,’ says Matthew J. Ward, vice president of construction at Intel. “We’re installing some of the world’s most sophisticated wafer fabrication processing equipment in this facility” that operates on the scale of just two nanometers (equivalent to the width of less than two dozen hydrogen atoms).…
