Where the article explains it
If each of n chiplets bonded into one package has an independent per-die yield , the assembly’s final yield is approximately
The passage around this formula
The arithmetic behind that claim is a plain probability composition, and it is worth writing down because it is the one piece of real math in advanced packaging that most design reviews skip past. If each of n chiplets bonded into one package has an independent per-die yield , the assembly’s final yield is approximately
