20150103426 | METHOD AND COOLING SYSTEM FOR COOLING AN OPTICAL ELEMENT FOR EUV APPLICATIONS - A method for cooling an optical element for EUV applications is disclosed. Heat is transferred from the optical element to a heat sink, and, via a first feed line, a first cooling medium is introduced into a cooling channel in the heat sink, in such a way that the first cooling medium effects laminar flow through the cooling channel and in the process absorbs heat from the heat sink. After flowing through the cooling channel, the first cooling medium is discharged into a discharge line leading away from the optical element. A second cooling medium is introduced into the discharge line via a second feed line, and the first cooling medium and the second cooling medium, downstream of the second feed line at a location that is further away from the optical element than the cooling channel, are subjected to a force field introduced into the discharge line externally. | 04-16-2015 |

20110235015 | ILLUMINATION OPTICS FOR EUV MICROLITHOGRAPHY - An illumination optics for EUV microlithography illuminates an object field with the aid of an EUV used radiation beam. Preset devices preset illumination parameters. An illumination correction device corrects the intensity distribution and/or the angular distribution of the object field illumination. The latter has an optical component to which the used radiation beam is at least partially applied upstream of the object field and which can be driven in a controlled manner. A detector acquires one of the illumination parameters. An evaluation device evaluates the detector data and converts the latter into control signals. At least one actuator displaces the optical component. During exposures, the actuators are controlled with the aid of the detector signals during the period of a projection exposure. A maximum displacement of below 8 μm is ensured for edges of the object field towards an object to be exposed. The result is an illumination optics that is used to ensure conformance with preset illumination parameters even given the most stringent demands upon precision. | 09-29-2011 |
