A method for manufacturing an integrated circuit includes scanning a wafer with respect to a catadioptric projection objective and imaging a pattern on a mask onto a wafer while scanning the wafer. The imaging includes illuminating the mask with radiation; imaging, using the radiation, the pattern into a first intermediate image, the first intermediate image to a second intermediate image, and the second intermediate image into an image field arranged in an image surface where the wafer is arranged; and, manipulating one or more of optical elements while scanning the wafer to reduce errors in the image at the image field. A concave mirror arranged in a region of a pupil surface reflects the radiation. The projection objective also includes mirrors to deflect the radiation from the object field towards the concave mirror and to deflect the radiation from the concave mirror towards the image field. The deflection mirrors are mechanically coupled to a displacement device arranged to displace the first and second deflection mirrors.

POST-OVERLAY COMPENSATION ON LARGE-FIELD PACKAGING
20240302752 · 2024-09-12 ·

A lithography challenge for large heterogeneous integration of integrated circuit devices is the limited size of the exposure field (typically 60 mm?60 mm or smaller) for most currently available lithography systems, Smaller-field systems can be used to pattern large substrates (e.g., panels) by stitching together multiple exposure fields. However, the stitching of exposure fields affects both productivity and yield because of the need for multiple exposures, which includes multiple reticles, and a risk of alignment errors at the stitching boundaries, A large-exposure field eliminates these problems associated with smaller exposure fields. However, there are also challenges associated with a large-exposure field, such as exposing onto a possibly warped or distorted panel. Various examples disclosed herein include a post-overlay compensation method that use an overlay-model prior to exposing the panel to reduce or eliminate errors due to the warped, or distorted panel. Other methods and systems are also disclosed.
