Abstract:
1. A process monitoring device of a semiconductor manufacturing apparatus comprising: a storage unit configured to store a normal state moving image data including a plurality of image frames and indicating a normal state of a process performed on a substrate in the semiconductor manufacturing apparatus by cutting out each of the plurality of image frames of the normal state moving image data; an image capturing unit configured to capture a moving image of a state of the process to be monitored to acquire a moving image data including a plurality of image frames; an abnormality level calculation unit configured to extract a feature amount for each frame of the moving image data acquired by the image capturing unit and each frame of the normal state moving image data, and calculate an abnormality level based on a difference between the extracted feature amount of the moving the image data acquired by the image capturing unit and the normal state moving image data; and a display unit configured to display the abnormality level calculated by the abnormality level calculation unit in association with a frame position of the moving image data acquired by the image capturing unit, allowing a user to identify a position where an abnormal event is occurred.
