Beschreibung
Zusammenfassung:	An extreme ultraviolet light (EUV) source apparatus includes a light source part for generating a plasma that emits EUV light; a first vacuum housing in which the light source part is located; a second vacuum housing arranged between the first vacuum housing and a utilizing apparatus in which the EUV light is utilized; and a debris trap located inside the second vacuum housing for deflecting debris particles emitted from the plasma, whereby the debris particles do not ingress into the utilizing apparatus. Between the first and second vacuum housings, there is provided a window through which the EUV light emitted from the light source part passes from the first vacuum housing to the second vacuum housing. A wall of the second vacuum housing has a through-hole and a window that is configured to allow the EUV light to pass from the second vacuum housing to the utilizing apparatus.
