Abstract:
Apparatus for semiconductor device fabrication, comprising:at least one lithography station, which is adapted to project a pattern of radiation from a mask onto a semiconductor wafer; a mask cleaning station, which is adapted to receive the mask from the at least one lithography station, to clean the mask so as to remove a contaminant therefrom, so that the cleaned mask may be transferred to the at least one lithography station; a robot, which is adapted to convey the mask between the at least one lithography station and the mask cleaning station; an enclosure, containing the at least one lithography station, the mask cleaning station and the robot, so that the mask is conveyed between the at least one lithography station and the mask cleaning station without human contact and without exposure to ambient air; and wherein the at least one lithography station comprises a plurality of exposure tools, commonly contained within the enclosure and served by the mask cleaning station.
