  • Patent number: 11953839
    Abstract: In a method of cleaning a lithography system, during idle mode, a stream of air is directed, through a first opening, into a chamber of a wafer table of an EUV lithography system. One or more particles is extracted by the directed stream of air from surfaces of one or more wafer chucks in the chamber of the wafer table. The stream of air and the extracted one or more particle are drawn, through a second opening, out of the chamber of the wafer table.

  • Publication number: 20230314963
    Abstract: A photolithographic apparatus includes a particle removing cassette, a pump and a compressor. The particle removing cassette includes a first slit that includes an array of parallel wind blade nozzles arranged along a length of the first slit, protruding from the first slit, and configured to eject and direct pressurized cleaning material to a patterning surface of a mask to remove debris particles on the patterning surface. The pump and the compressor are controlled by a controller to adjust a flow rate and a pressure of the pressurized cleaning material based on an amount of debris particles on the patterning surface of the mask.

  • Patent number: 11698592
    Abstract: An photolithographic apparatus includes a particle removing cassette selectively extendable from the processing apparatus. The particle removing cassette includes a wind blade slit and an exhausting slit. The wind blade slit is configured to direct pressurized cleaning material to a surface of the mask to remove the debris particles from the surface of the mask. The exhausting slit collects the debris particles separated from the surface of the mask and contaminants through the exhaust line. In some embodiments, the wind blade slit includes an array of wind blade nozzles spaced apart within the wind blade slit. In some embodiments, the exhausting slit includes array of exhaust lines spaced apart within the exhausting slit.
