Abstract
Embodiments of the present disclosure provide an apparatus including mask pattern formed on a mask substrate. A plurality of spatial radiation modulators may be vertically displaced from the mask pattern, and distributed across a two-dimensional area. Each of the plurality of spatial radiation modulators may be adjustable between a first transparent state and a second transparent state to control whether radiation transmitted through the mask pattern passes through each of the plurality of spatial radiation modulators.
