Defect Inspection
Defect Inspection is a crucial quality control process in making computer chips and electronic components. It involves checking for any problems or imperfections in semiconductors (computer chips) during manufacturing. Think of it like quality control in a bakery, but instead of checking pastries, workers examine tiny electronic parts using special microscopes and automated inspection tools. This process helps ensure that the chips going into computers, phones, and other electronics work properly. Workers might use terms like "wafer inspection," "visual inspection," or "automated optical inspection" to describe this work.
