Publication number: 20220059382Abstract: A method and an apparatus for detecting positions of wafers. A rotation table, on which the wafer with an aiming feature is disposed, rotates in a direction at a faster speed while a detector detects a periphery of the wafer and provides a controller with a detection result. The rotation table rotates in an opposite direction at a slower speed after the aiming feature passes the detector, while the detector detects the periphery of the wafer and provides the controller with a new detection result. A respective detection result corresponds to a rotation angle. When the aiming feature passes the detector again, the rotation table stops rotating, and the controller computes the eccentric position of the wafer and the position of the aiming feature according to the detection results and their rotation angles. Therefore, the time for detection may decrease.Type: ApplicationFiled: May 3, 2021Publication date: February 24, 2022Inventors: Yan-Yu Chen, Ming-Shiou Liu
