Abstract: An automatic teaching apparatus for semiconductor manufacturing equipment includes: an equipment front end module (EFEM); one or more load ports provided along an edge of one side of the EFEM to be connected to an inside of the EFEM; a transfer robot disposed in the inside of the EFEM and configured to transfer a wafer to the one or more load ports by an end effector to process the wafer, and a load port teaching unit configured to detect a fixed position of the end effector in a state of unloading the wafer such that the wafer is placed in the fixed position within the load port.
