Abstract
Embodiments of the present disclosure generally relate to methods and apparatus for processing one or more substrates, and more specifically to improved spatial light modulators for digital lithography systems and digital lithography methods using improved spatial light modulators. The spatial light modulator is configured such that there is a 180-degree phase shift between adjacent spatial light modulator pixels. The spatial light modulator is useful for pixel blending by forming a plurality of partially overlapping images, at least one of the plurality of partially overlapping images having at least two pixels formed by a first pair of adjacent spatial light modulator pixels having a 180-degree phase shift therebetween. The spatial light modulator results in improved resolution, depth of focus, and pixel blending.
