Title: Positioner
Inventor: ONO KAZUYA
IPC: G03F7/20
Filed: 1990-10-02
Abstract: PURPOSE:To improve accuracy by measuring the position of X-Y stage and determining in advance the shift of length axis in X and Y direction, from the point to be positioned. CONSTITUTION:Beneath the Y stage, an X mirror 9 and a Y mirror 10 are fixed. These are used as mirrors for a laser interference meter to measure the movements of a wafer 8 in X and Y directions and pitching, rolling and yawing directions. And the rotations around Y axis, and Z axis and displacement toward X axis are measured with lasers 11 through 13. Based on these detection results and the distance between the movement measuring position on each of X and Y directions measured in advance and the standard point of positioning, a true movement to each of X and Y directions are calculated. By measuring in advance the shift of length axis on X, Y directions from the point to be positioned in this manner, accuracy is improved.
