Publication number: 20240134291Abstract: A processing apparatus for overlay shift includes a storage unit and a control unit, and is applicable to a semiconductor wafer with several inspection regions. Each of the inspection regions has several sets of overlay marks for inspection. One set of overlay marks includes an original alignment mark without any overlay shift, and several split alignment marks with predetermined overlay shifts arranged near the original alignment mark. The original after-etch inspection (AEI) overlay data of the inspection regions is stored in the storage unit. The after-develop inspection (ADI) overlay data of the original alignment mark and the split alignment marks are compared with the original AEI overlay data by the control unit, thereby acquiring ADI pre-bias data of the original alignment mark and the split alignment marks. The control unit determines whether an overlay shift compensation is performed according to the acquired ADI pre-bias data.Type: ApplicationFiled: October 12, 2023Publication date: April 25, 2024Inventors: Meng-Hsien TSAI, Cheng-Shuai LI, Yueh-Feng LU, Kao-Tsair TSAI
