A shutter is provided near the immediate focus of a lithography apparatus in order to deflect tin debris generated by a source side of the apparatus away from a scanner side of the apparatus and towards a debris collection device. The activation of the shutter is synchronized with the generation of light pulses so as not to block light from entering the scanner side.

A lithography system is provided capable of deterring contaminants, such as tin debris from entering into the scanner. The lithography system in accordance with various embodiments of the present disclosure includes a processor, an extreme ultraviolet light source, a scanner, and a hollow connection member. The light source includes a droplet generator for generating a droplet, a collector for reflecting extreme ultraviolet light into an intermediate focus point, and a light generator for generating pre-pulse light and main pulse light. The droplet generates the extreme ultraviolet light in response to the droplet being illuminated with the pre-pulse light and the main pulse light. The scanner includes a wafer stage. The hollow connection member includes an inlet that is in fluid communication with an exhaust pump. The hollow connection member provides a hollow space in which the intermediate focus point is disposed. The hollow connection member is disposed between the extreme ultraviolet light source and the scanner.
