Abstract:
Method and system configured to reduce or even nullify the degradation of images created by the projector tool turns on the optimization of the pattern-imaging by adjusting parameters and hardware of the projector to judiciously impact the placement of various image edges at different locations in the image field. Adjustments to the projector (exposure tool) include a change of a setup parameter of the exposure tool and/or scanning synchronization and/or a change of a signature of the optical system of the exposure tool determined as a result of minimizing the pre-determined cost function(s) that are parts of a comprehensive edge-placement error model.

Claim (Index 36):
A system for predicting and monitoring a position of an edge of a pattern image formed on a wafer, the system comprising:\n a lithographic exposure tool including\n a wafer-positioning apparatus configured to support said wafer, move said wafer with respect to a chosen reference position, and register movements of said wafer with the use of an optical interferometer;\n an illumination system containing \n a reticle, and \n an optical system configured to illuminate said reticle in a direction of said wafer; \n \n a projection optics configured to image said reticle on said wafer; and an optical detection unit configured to acquire a distribution of light irradiance, at a chosen plane within said exposure tool, as a function of location across at least one of said reticle and said wafer; \n and\n a computing device operably connected with the lithographic exposure tool and configured to: \n create an exposure dose map and an image defocus map based on data that represent \n optical irradiance distribution across the wafer and have been acquired, with the use of said optical detection unit, from at least one exposure run that creates said pattern image on the wafer; and \n determine critical dimension and image shift values of said pattern image based on \n (i) the exposure dose map, (ii) the image defocus map, (iii) predetermined first relationships among image defocus and exposure dose and the critical dimensions, and (iv) predetermined second relationships among image defocus and expose dose and a the image shift.
