Patent ID: 7349067

Claim:
A lithographic apparatus, comprising: (a) a processing unit configured to process a substrate, the processing unit comprising: an illumination system that provides a beam of radiation; a support structure configured to support a patterning device that imparts a desired pattern to the beam of radiation; a substrate holder configured to hold the substrate; a projection system configured to project the patterned beam onto a target portion of the substrate; and (b) a track interface arranged adjacent the processing unit in which the patterned beam is projected onto the target portion of the substrate, the track interface having a loading station configured to hold more than one substrate to be processed by the processing unit and a discharge station configured to hold a substrate processed by the processing unit; (c) a transfer unit arranged in the track interface and comprising more than one robot configured to directly transfer the substrate to be processed from the loading station to the processing unit and to directly transfer the substrate processed from the processing unit to the discharge station.
