Taiwan Semiconductor Manufacturing Company’s first Arizona chip fabrication plant, or fab, is making history because it’s the most advanced chip fab on U.S. soil, and Apple has committed to being the site’s largest customer. The company initially announced the plant would cost $12 billion and pump out 5-nanometer chips by the end of 2024. Three years later, that price tag has soared to $20 billion, and full production is delayed until 2025.
