Abstract

Wave-optical effects are becoming more pronounced as optical lithography is pushed towards its limit. Photomask topography scattering and wafer polarization effects caused by differences in coupling between transverse electric and transverse magnetic waves degrade image quality. But polarization may provide an extra dimension that allows lithographers to devise simple solutions to otherwise difficult problems such as phase assignment.
