Abstract: 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.
