Process monitoring device and process monitoring method in semiconductor manufacturing apparatus and semiconductor manufacturing apparatus

摘要

Provide is a process monitoring device in a semiconductor manufacturing apparatus that can readily and reliably monitor the process in the semiconductor manufacturing apparatus. The process monitoring device includes a storage unit that stores a normal state moving image data indicating a normal state of the process; an image capturing unit that captures an image of a state of the process to be monitored to acquire a moving image data; an abnormality level calculation unit configured to extract a feature amount for each frame of the moving image data and the normal state moving image data, and calculate an abnormality level based on the extracted feature amount; and a display unit that displays the abnormality level calculated by the abnormality level calculation unit in association with a frame position of the moving image data.
