  • Patent number: 11367636
    Abstract: A substrate transfer device and method as well as a photolithography apparatus are disclosed. The device includes a motion platform and a plurality of transfer stages which are arranged side-by-side along a first direction are configured to transfer substrates in a second direction that is perpendicular to the first direction. The motion platform includes a base table and a plurality of motion tables in movable connection with the base table. Each of the transfer stages is connected to, and movable in the first direction with, a corresponding one of the motion tables. A pre-alignment assembly for pre-alignment and positional adjustments of the substrates is provided on the motion platform and on the transfer stages. When one of the transfer stages is unloading a first substrate, another one of the transfer stages receives a second substrate and effectuates its first- and second-directional pre-alignment with the aid of the pre-alignment assembly.
