Abstract:
A photolithography tool and a method for compensating for surface deformation in a carrier of the photolithography tool are disclosed. In the photolithography tool, carrier surface deformation compensation elements are provided at the bottom of the carrier, which are capable of compensating for the surface deformation in the carrier. In the method, the surface deformation is detected by carrier surface deformation detection modules, and an automated closed-loop controller controls compensating forces exerted by the carrier surface deformation compensation elements based on the detected deformation. This allows more accurate compensation for the carrier surface deformation.

Claim (Index 8):
A method for compensating for surface deformation in a carrier of a photolithography tool, comprising:\n 1) providing carrier surface deformation detection modules at a bottom of the carrier; 2) recording data detected by the carrier surface deformation detection modules and compensating forces exerted by carrier surface deformation compensation elements to the carrier that cause strains generated from the surface deformation of the carrier to be less than a threshold; 3) stepping the wafer stage, and repeating step 2) for each step until a farthest point of the wafer stage is reached; 4) least-square fitting the date recorded in steps 2) and 3); and 5) providing an automated closed-loop controller that is connected to the carrier surface deformation compensation elements and configured to control the compensating forces exerted by the carrier surface deformation compensation elements during movement of the wafer stage based on the fitted data obtained in step 4).
