Claim:
1. A method for processing a wafer, comprising: placing the wafer on a transferring module having two wafer blocks portions, wherein the distance between the first of the wafer block portion and the edge of the wafer is shorter than the distance between the second of the wafer block portion and the edge of the wafer; transmitting a first positioning data to the transferring module to enable the transferring module to send the wafer into a processing chamber; recording an image feature in relation to the wafer; determining a second positioning data based on the image feature; transmitting the second positioning data to the transferring module to enable the transferring module to place the wafer in a processing position; and performing a processing operation over the wafer which is located in the processing position.
