Where the article explains it
If a bonded interface carries N individual interconnects and each has an independent probability of a bonding defect — misalignment, particle contamination, or a void — then the probability the whole interface bonds cleanly falls as
The passage around this formula
That second half of the trade is where yield risk concentrates. If a bonded interface carries N individual interconnects and each has an independent probability of a bonding defect — misalignment, particle contamination, or a void — then the probability the whole interface bonds cleanly falls as
Learn the underlying idea
A variable is a named place for a value. Its letter is a local label: x can mean position in one formula and a data point in another.
