Where the article explains it
with defect density , die area A , and a clustering parameter c that captures the fact that defects are not independently scattered [ 2 ] .
The passage around this formula
…that a given die contains none of them falls as its area grows. Feng and Ma, in the cost model they published for multi-chiplet architectures, use the negative binomial form . with defect density , die area A , and a clustering parameter c that captures the fact that defects are not independently scattered [ 2 ] . The exact parameters matter less than the shape. Yield falls monotonically with area, so cost per good die rises faster than area, and past some size the marginal square…
