Abstract: A method and an apparatus for transferring wafers are provided to reduce a centering time of the wafer transferring apparatus by compensating for a target position based on a detection position. An apparatus for transferring wafers transfers the waveform, which is extracted from a wafer cassette, to a reactor and includes a wafer transfer unit(40), at least three sensors, and a controller. The wafer transfer unit includes an arm, which supports the wafers and transfers the wafer to the reactor. The wafers are contained in the wafer cassette. The sensors are arranged to be apart from each other in a direction parallel to a transfer direction of the wafer. The sensors are arranged at an outlet hole of the wafer cassette. The controller determines whether a target position, which is calculated based on detection signals from the sensors and a transfer speed of the arm, is different from a detection position. The controller compensates for the target position based on the detection position of the wafer, such that the wafer is delivered to the reactor by the wafer transfer unit.
