摘要： The exposure device is able to supply only EUV radiation to a mask, while eliminating radiation other than the EUV radiation. A multi layer made from a plurality of Mo/Si pair layers is provided upon the front surface of a mirror, and blazed grooves are formed in this multi layer. Radiation which is incident from a light source device is incident upon this mirror, and is reflected or diffracted. Since the reflected EUV radiation (including diffracted EUV radiation) and the radiation of other wavelengths are reflected or diffracted at different angles, accordingly their directions of progression are different. By eliminating the radiation of other wavelengths with an aperture and/or a dumper, it is possible to irradiate a mask only with EUV radiation of high purity.
摘要翻译：曝光装置只能将EUV辐射提供给掩模，同时消除EUV辐射以外的辐射。在反射镜的前表面上设置由多个Mo / Si对层制成的多层，并且在该多层中形成闪耀的凹槽。从光源装置入射的辐射入射在该反射镜上并被反射或衍射。由于反射的EUV辐射（包括衍射的EUV辐射）和其他波长的辐射以不同的角度被反射或衍射，因此它们的进展方向是不同的。通过用孔和/或自卸车消除其它波长的辐射，可以仅用高纯度的EUV辐射照射掩模。

摘要： An EUV light source of the present invention is capable of using a saturable absorber stably and continuously in a high heat load state. A saturable absorber (SA) device is disposed on a laser beam line to absorb feeble light, such as self-excited oscillation light, parasitic oscillation light or return light. SA gas from an SA gas cylinder and buffer gas from a buffer gas cylinder are mixed to be a mixed gas. The mixed gas is supplied to an SA gas cell via a supply pipeline, and absorbs the feeble light included in the laser beam. The mixed gas is exhausted via an exhaust pipeline, and is sent to a heat exchanger. The mixed gas, cooled down by a heat exchanger, is sent back to the SA gas cell by a circulation pump.
