The passage around this formula
…a defect density that would look damaging if it were spread evenly. Which model actually fits a given fab’s data is an empirical question the fab’s yield-management team answers continuously, not a constant chosen once — itself falls over the life of a node as the “yield learning curve” progresses, and a large part of a fab’s early operating cost on any new node is spent buying that learning curve down before volume production.
