Metrology
Metrology is the science of measuring and inspecting things with extreme precision in semiconductor manufacturing. Think of it like quality control, but at a microscopic level. When companies make computer chips and electronic components, they need to make sure every tiny part is exactly the right size and shape - sometimes down to measurements smaller than a human hair. Metrology specialists use advanced measuring equipment and techniques to check that everything meets strict standards. This is crucial because even tiny mistakes in chip manufacturing can make the final product fail.
