  • Publication number: 20230099309
    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: 20220299883
    Abstract: An extreme ultraviolet (EUV) photolithography system detects debris travelling from an EUV generation chamber to a scanner. The photolithography system includes a detection light source and a sensor. The detection light source outputs a detection light across a path of travel of debris particles from the EUV generation chamber. The sensor senses debris particles by detecting interaction of the debris particles with the detection light.
