摘要： A radiation source comprising a fuel source configured to deliver fuel to a location from which the fuel emits EUV radiation. The radiation source further comprises an immobile fuel debris receiving surface provided with a plurality of grooves. The grooves have orientations which are arranged to direct the flow of liquid fuel under the influence of gravity in one or more desired directions.

摘要： A radiation system comprises a fuel emitter configured to provide fuel to a plasma formation region, a laser arranged to provide a laser beam at the plasma formation region incident on the fuel to generate a radiation emitting plasma, and a reflective or transmissive device (30) arranged to receive radiation emitted by the plasma and to reflect or transmit at least some of the received radiation along a desired path, wherein the reflective or transmissive device comprises a body configured to reflect and/or transmit said at least some of the radiation, and selected secondary electron emission (SEE) material (34) arranged relative to the body such as to emit secondary electrons in response to the received radiation, thereby to clean material from a surface of the device.32

摘要： A radiation source suitable for providing radiation to a lithographic apparatus generates radiation from a plasma (12) generated from a fuel (31) within an enclosure comprising a gas. The plasma generates primary fuel debris collected as a fuel layer on a debris-receiving surface ((33a), (33b)). The debris-receiving surface is heated to a temperature to maintain the fuel layer as a liquid, and to provide a reduced or zero rate of formation gas bubbles within the liquid fuel layer in order to reduce contamination of optical surfaces (14) by secondary debris arising from gas bubble eruption from the liquid fuel layer. Additionally or alternatively, the radiation source may have a debris receiving surface positioned and/or oriented such that substantially all lines normal to the debris receiving surface do not intersect an optically active surface of the radiation source.
