摘要: An extreme ultraviolet light system includes a drive laser system that produces an amplified light beam; a target material delivery system configured to produce a target material at a target location; a beam delivery system configured to receive the amplified light beam emitted from the drive laser system and to direct the amplified light beam toward the target location; and a metrology system. The beam delivery system includes converging lens configured and arranged to focus the amplified light beam at the target location. The metrology system includes a light collection system configured to collect a portion of the amplified light beam reflected from the converging lens and a portion of a guide laser beam reflected from the converging lens. The light collection system includes a dichroic optical device configured to optically separate the portions.

摘要: A protector for a viewport of a vacuum chamber includes a substrate material that absorbs radiation having a wavelength of an amplified light beam and radiation having a wavelength included in an emission spectra of a target material that produces EUV light when ionized by the amplified light beam. The substrate material transmits one or more of visible or near-infrared light. The protector also includes a layer formed on the substrate material, and the layer reflects radiation having the wavelength of the amplified light beam.
