Wafer inspection is a critical step in semiconductor manufacturing, ensuring the quality and reliability of integrated circuits. It involves a series of rigorous tests and examinations performed at various stages of the fabrication process to detect defects, contamination, and deviations from specified parameters. These inspections utilize a range of techniques, including optical microscopy, scanning electron microscopy (SEM), and automated optical inspection (AOI) systems, to identify issues such as scratches, particles, and structural imperfections. The data gathered during inspection helps to optimize manufacturing processes, improve yield, and prevent defective wafers from progressing further in the production line, saving time and resources.
Wafer inspection is vital in semiconductor manufacturing, ensuring the quality and reliability of electronic devices. This process identifies defects on wafers, which are thin slices of semiconductor material.
