    摘要: Devices and corresponding methods of use are described herein which may comprise an enclosing structure defining a closed loop flow path and a system generating a plasma at a plasma site, e.g. laser produced plasma system, where the plasma site may be in fluid communication with the flow path. For the device, a gas may be disposed in the enclosing structure which may include an ion-stopping buffer gas and/or an etchant. A pump may be provided to force the gas through the closed loop flow path. One or more heat exchangers removing heat from gas flowing in the flow path may be provided. In some arrangements, a filter may be used to remove at least a portion of a target species from gas flowing in the flow path.

    摘要: A device is disclosed which may comprise a system generating a plasma at a plasma site, the plasma producing EUV radiation and ions exiting the plasma. The device may also include an optic, e.g., a multi-layer mirror, distanced from the site by a distance, d, and a flowing gas disposed between the plasma and optic, the gas establishing a gas pressure sufficient to operate over the distance, d, to reduce ion energy below a pre-selected value before the ions reach the optic. In one embodiment, the gas may comprise hydrogen and in a particular embodiment, the gas may comprise greater than 50 percent hydrogen by volume.

    摘要: An LPP EUV light source is disclosed having an optic positioned in the plasma chamber for reflecting EUV light generated therein and a laser input window. For this aspect, the EUV light source may be configured to expose the optic to a gaseous etchant pressure for optic cleaning while the window is exposed to a lower gaseous etchant pressure to avoid window coating deterioration. In another aspect, an EUV light source may comprise a target material positionable along a beam path to participate in a first interaction with light on the beam path; an optical amplifier; and at least one optic directing photons scattered from the first interaction into the optical amplifier to produce a laser beam on the beam path for a subsequent interaction with the target material to produce an EUV light emitting plasma.
