Abstract: PURPOSE:To facilitate highly accurate positioning of a semiconductor wafer under noncontact conditions without being influenced by the variation of the diameter of the semiconductor wafer and the length of the orientation flat by a method wherein rotation angle information and information based upon the position of the orientation flat of the semiconductor wafer obtained by a noncontact type sensor are processed. CONSTITUTION:A semiconductor water 1 is placed on a chuck 5 and a depressurizing part 8 linked with the chuck 5 is driven to fix the wafer 1. The position of the orientation flat 1' of the semiconductor wafer 1 is obtained by a noncontact type sensor 12 provided near the outer circumference of the semiconductor wafer 1. The reflecting type or transmitting type sensor 12 is employed. If the former one is used, a light from a light projecting part is reflected by the rear of the semiconductor wafer 1 except the orientation flat 1' and detected by a light detecting part and the sensor is turned ON. In this stage, the semiconductor wafer 1 is rotated clockwise and stopped when the sensor 12 is turned ON from OFF to detect the orientation flat 1'. Then the semiconductor wafer 1 is rotated counter-clockwise to calculate the rotation angle thetafrom the previous state and then the semiconductor wafer 1 is rotated again by the angle theta/2 to complete the positioning. By means of this constitution, the operation with a high positioning accuracy can be achieved.
