Milestone: first 2nm-class volume output outside Taiwan, base 2030 / aggressive 2028, from TSMC Arizona's phase-3 fab (begun April 2025) plus a 2-4 year build and a 6-12 month yield ramp.

Evidence 2 passages

• groundsSource document

  Despite their size and complexity, fabs are built surprisingly quickly, around two to four years on average.

• groundsSource document

  once tooling is installed, it might take six months to a year of ramp up before the fab is hitting acceptable process yields.
