Patent ID: 8473095

Claim:
A substrate processing apparatus comprising: at least one sensor provided in each axis of a transfer mechanism configured to transfer a substrate; a transfer control module comprising a storage means for temporarily storing a sensed data received from each of the at least one sensor; and a manipulation unit at least comprising a display unit for displaying a state of the transfer mechanism based on the sensed data, wherein the transfer control module is configured to store the sensed data from a start of an operation of the transfer mechanism to a termination of the operation of the transfer mechanism in the storage means while operating the transfer mechanism, delete the sensed data when a detection result data detected by the at least one sensor indicates the operation is OK at the termination of the operation of the transfer mechanism, and store the sensed data in the storage means when the detection result data detected by the at least one sensor indicates the operation is NG at the termination of the operation of the transfer mechanism, and wherein the manipulation unit displays at least the sensed data detected by the at least one sensor on the display unit when the operation is NG.
