Abstract: Embodiments of the present disclosure generally provide a digital lithography system that can process both large area substrates as well as semiconductor device substrates, such as wafers. Both the large area substrates and the semiconductor device substrates can be processed in the same system simultaneously. Additionally, the system can accommodate different levels of exposure for forming the features over the substrates. For example, the system can accommodate very precise feature patterning as well as less precise feature patterning. The different exposures can occur in the same chamber simultaneously. Thus, the system is capable of processing both semiconductor device substrates and large area substrates simultaneously while also accommodating very precise feature patterning simultaneous with less precise feature patterning.
