Abstract:
Provided is an intelligent correction device control system for a super-resolution lithography precision mask, including: a sixteen-way pneumatic fine-tuning mask deformation control subsystem configured to deform a mask, detect a force value of a mask deformation, compare the force value of the mask deformation with an output force set value, and generate a first control feedback quantity to adjust a force deforming the mask, so as to control a deformation quantity of the mask; and an alignment subsystem configured to acquire images of the mask and a substrate, and adjust a position between the mask and the substrate according to the images, so as to align the mask with the substrate.
