Abstract
A loader module of a substrate processing system includes a transportation arm configured to move towards a wafer accommodated in a carrier and receive the wafer, and a control unit configured to confirm a delivery position of the wafer based on an upward movement amount of an end effector of the transportation arm, and a contact sound generated when the end effector comes in contact with the wafer. The control unit confirms the delivery position of the wafer based on an average height of the end effector when the contact sound of each pad of the end effector comes in contact with the wafer to generate a contact sound a plurality of times.
