Why does moving the measurement change the verdict on a machine? →Open a dishwasher after its first drain, then remove the bread from a toaster. Two small experiments expose where a measurement begins, where it ends and what the instrument actually senses.This video helps answer · What goes on the mask if the wafer needs an L?How far is one working chip from a viable production line? →Work backward from a die that passed test. How many others passed on that wafer? Who qualified the machinery? Was the line under financial pressure before an interruption?This video helps answer · A corrected mask still needs light on the wafer
Caption notes
QueueTard starts from a concrete mismatch: an L drawn on a mask prints with distorted corners on a wafer. He uses that example to explain optical proximity correction within a tour of clean rooms, lithography, etching and the search for manufacturing defects.

you'd think I'd put that L shape on a mask.That shape is numerically determined, basically calculated in a supercomputer.
