Abstract
A method, apparatus, and system for controlling a reticle-masking blade in a photolithography system. A reticle-masking blade is supported with a reticle-masking blade carriage assembly. The reticle-masking blade carriage assembly is levitated at a position with respect to a reference frame and at an orientation with respect to the reference frame. Preferably, the reticle-masking blade carriage assembly is electromagnetically levitated. At least one of the position and the orientation of the reticle-masking blade carriage assembly is measured. At least one of the position and the orientation of the reticle-masking blade carriage assembly is controlled. Optionally, the reticle-masking blade carriage assembly is moved within a dimension within a range defined by the reference frame. The dimension can be two dimensions. The movement of the reticle-masking blade carriage assembly can be controlled.
