Claim 3:
4. The wafer transfer module in the semiconductor manufacturing machine according to claim 3, wherein if an acceptable vertical tolerance for the position of the to-be-transferred wafer with respect to a wafer target position S is h2, a distance X2 between the first transmitter and the second transmitter is d4+d1+2*h2, and the wafer target position S is a position where the to-be-transferred wafer can be transferred in the case of no deviation of the transfer arm, without a scratch on the to-be-transferred wafer and on a wafer on a lower side adjacent to the to-be-transferred wafer.
