Equation 7 · Part 1 · Chiplets and Advanced Packaging in 2035: Scenarios, Signals, and Falsifiable Predictions
Symbol p^2
What this part means
the square of p; the pitch.
Its job in the formula
is squared: multiply the underlying quantity by itself. The square is a mathematical operation, not a second independent variable.

Where the article explains it
For interconnects arranged on a roughly square grid at pitch p , the number of connections available per unit of bonding area scales as \;\; .
The passage around this formula
Because N itself grows as roughly 1/ under the density relation above, falls unless the per-interconnect defect probability improves at least as fast as the pitch shrinks — which is precisely the motivation behind Chen and Gupta’s YAP+ framework, a pad-layout-aware yield model for copper-copper hybrid bonding that accounts for misalignment, particle contamination, copper recess variation, surface roughness and pad density across arbitrary layouts, and reports a near-analytical model matching full physical-simulation accuracy at more than a thousand-fold speed-up in runtime [ 11 ] . A fast, accurate yield model of this kind is itself a signal about where the field…
Learn the underlying idea
An exponent tells how a base is used in multiplication. In x³, x is the base and 3 is the exponent: x³ = x × x × x.
