A multiple substrate orienter is provided that includes a rotatable substrate handler having a plurality of substrate support portions, each adapted to support a substrate. The multiple substrate orienter also includes a plurality of stacked substrate supports, each adapted to support a substrate. A plurality of substrate orientation marking (SOM) detectors are provided, and each SOM detector is coupled to a different one of the substrate supports and is adapted to identify a presence of an SOM of a substrate positioned close enough to the SOM detector to allow SOM detection by the SOM detector. The multiple substrate orienter further includes a plurality of lift and lower mechanisms, each lift and lower mechanism coupled to a different one of the substrate supports and adapted to individually lift and lower the substrate support to which the lift and lower mechanism is coupled. Numerous other aspects are provided.
