The passage around this formula

…bonder alignment tolerance, planarization quality, and interposer warpage control mature. This is why the practice described across the preceding three gates functions as one system: tightening KGD screening raises the yiy_i terms, tightening bonder alignment and thermomechanical control raises the assembly-yield term, and only both together make the arithmetic work at the die counts modern AI accelerator packages actually use.
