Abstract: PROBLEM TO BE SOLVED: To set a second direction at an arbitrary position without adding another position detection means by positioning a wafer which is positioned in a first direction from rotation and dislocation in an ordinary direction of a board in a second direction by calculating movement and rotation amount in a plane parallel to the wafer surface. SOLUTION: An X-stage and a Y-stage are driven to a stage center S independently, the number of pulses to the stage center S is counted, coordinates C1 (x1, y1) are obtained and a wafer is positioned in a first direction. Then, 90 deg. rotated position C2 (x2, y2) is calculated from the equation with θ=90 deg. and a wafer chuck is driven from a stage center S to C2 (x2, y2). Therefore, positional relation between a wafer center W1 in positioning in a first direction and a wafer center W3 in positioning in a second direction is constant regardless of a wafer chuck position and position reproducibility in a second direction can be obtained. Thereby, a second direction can be set at an arbitrary position without adding another position detection means.
