Reserving spatial light modulator sections to address field non-uniformities

Embodiments of the present disclosure generally provide improved photolithography systems and methods using a digital micromirror device (DMD). The DMD comprises columns and rows of micromirrors disposed opposite a substrate. Light beams reflect off the micromirrors onto the substrate, resulting in a patterned substrate.
