  • Publication number: 20240134291
    Abstract: 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.

  • Publication number: 20240085172
    Abstract: The device includes a projecting device, an image sensor and a computing circuit. The projecting device provides a light beam having a predetermined pattern that is projected onto an object. The image sensor receives the light beam reflected from the object to generate an image. The computing circuit compares the image with a first ground-truth image and a ground-truth image to generate a first depth value and a second depth value respectively. The first and second depth values are combined to generate a depth result.
