Filed: 1989-12-20
Abstract: PURPOSE:To enable aligning operation even when the shape of a semiconductor wafer is incomplete by detecting the distance between the center and edge of rotation of a body to be detected at predetermined angle intervals, detecting variation in the distance, and detecting the position of a straight part. CONSTITUTION:When the semiconductor wafer 1 is rotated at intervals of an angle alpha as shown by an arrow, the angle alpha is set to <=1/3 the angle intervals that an orientation flat 2 as the straight part occupies. Therefore, the rotation is stopped on the flat 2 at least three points and the three points on the flat 2 become measurement points. Assuming that the center O of the rotation is in the center of the wafer 1, the triangle OAB formed of edge points A and B not on the flat 2 and the center O is an isosceles triangle. Further, the tri angle OCD formed of two points C and D on the flat 2 and the center O is expressed by acute angleOCD+acute anglealpha = acute angleODE. Therefore, the wafer is rotated at intervals of the angle alpha and it is decided whether the equation holds for the triangle formed of the center O and current edge, and the edge before it, thereby detecting the position of the flat 2.
