Abstract:
A method comprising:providing a multiple substrate orienter having: a rotatable substrate handler having a plurality of substrate support portions, each adapted to support a substrate; a plurality of stacked substrate supports, each substrate support adapted to support a substrate; a plurality of substrate orientation marking (SOM) detectors, each SOM detector coupled to a different one of the substrate supports and 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; and 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 different one of the substrate supports; rough orienting a plurality of substrates via at least the rotatable substrate handler; and fine orienting each rough oriented substrate via at least the rotatable substrate handler and the plurality of stacked substrate supports.
