A "First Tool-In" ceremony at the TSMC facility under construction in Phoenix, Arizona, US, on December 6, 2022. Despite its dominance of chip design, America is racing to build chipmaking fabs onshore. Intel is revamping its foundry business, building two new fabs in Arizona and a pair of fabs at its Ohio megasite. Last year, TSMC unveiled its US plans, adding a second Arizona fab and investing billions to start production in 2026. In Oct 2022, Micron announced its plans to spend $20 billion to build the largest ever US semiconductor factory, a memory chip fabrication plant in New York's Onondaga County, the size of 40 football fields and create about 50,000 jobs.
