Abstract: Disclosed is a system for generating EUV radiation in which current flowing through target material in the orifice 320 of a nozzle in a droplet generator is controlled by providing alternate lower impedance paths for the current and/or by limiting a high frequency component of a drive signal applied to the droplet generator.

Abstract: Apparatus for and method of accelerating droplets used to generate EUV radiation that comprise an arrangement producing a laser beam directed to an irradiation region and a droplet source. The droplet source includes a fluid exiting a nozzle in a stream that breaks up into droplets that then undergo coalescence. The droplets are then subjected to a stream of gas that entrains and accelerates the droplets.

Abstract: A target delivery system for an extreme ultraviolet (EUV) light source is disclosed. The system includes: a conduit including an orifice configured to fluidly couple to a reservoir; an actuator configured to mechanically couple to the conduit such that motion of the actuator is transferred to the conduit; and a control system coupled to the actuator, the control system being configured to: determine an indication of pressure applied to target material in the reservoir, and control the motion of the actuator based on the determined indication of applied pressure. Moreover, techniques for operating a supply system are disclosed. For example, one or more characteristics of the supply system are determined, and an actuator that is mechanically coupled to the supply system is controlled based on the one or more determined characteristics such that an orifice of the supply system remains substantially free of material damage during operational use.

Abstract: An apparatus includes: a tube; a body including: a first body wall and a second body wall; and a support structure including: a first support portion and a second support portion. The first body wall extends in a first direction, the second body wall extends in a second direction that is different than the first direction, a first portion of the tube passes through an opening in the second body wall the first support portion is configured to attach to the first body wall, and a second portion of the tube is configured to pass through the second support portion when the first support portion is attached to the first body wall. An interior of the tube and an interior of the body are configured to receive molten target material, and the target material emits extreme ultraviolet (EUV) light when in a plasma state.
