Abstract: A target material supply apparatus for an extreme ultraviolet (EUV) light source includes a tube that includes a first end, a second end, and a sidewall defined between the first and second ends. At least a portion of an outer surface of the tube includes an electrically insulating material, the first end receives a pressurized target material, and the second end defines an orifice through which the pressurized target material passes to produce a stream of target material droplets. The target material supply apparatus also includes an electrically conductive coating on the outer surface of the tube. The coating is configured to electrically connect the outer surface of the tube to ground to thereby reduce surface charge on the outer surface.
