    摘要: The invention describes a particle-optical apparatus arranged to focus a beam (1) of electrically charged particles with the aid of two particle-optical lens systems (10, 20). The lens action is achieved by magnetic fields, which fields are generated by permanent-magnetic materials (13, 23). In contrast to magnetic lenses equipped with a coil, it is not easy in the case of lenses equipped with permanent-magnetic material to alter the focusing magnetic field with the aim of altering the optical power. In an apparatus according to the invention, the optical power of the lens systems is altered by altering the energy with which the beam (1) traverses the lens systems (10, 20). This can easily happen by altering the voltage of electrical power supplies (14, 24).

    摘要: A method of generating EUV radiation is described, comprising the steps of: transporting a solid medium (33) through a source space (34) connected to a vacuum pump (35), and irradiating a portion (37) of the medium with an intense, pulsed, laser beam (41) focused on said portion of the medium, thus creating a plasma (47) which emits EUV radiation. To increase the intensity of the EUV radiation and improve the possibility to collect particles (51, 52, 53) released from the medium, at least the medium portions (37) to be irradiated have a concave shape. The method can be improved by embedding the medium in a flow of rare gas. Also described are a EUV radiation source unit for realizing the method and the application of the method in the manufacture of devices such as IC devices, and in a lithographic projection apparatus.

    摘要: The invention relates to an apparatus for evacuating samples. A sample 4 is hereby placed in a cavity 3 of a sheet 1 with a smooth surface 2. A sole plate 5 Is placed upon this smooth surface 2, whereby the smooth surface 2 and the sole plate 5 placed thereupon together form a vacuum seal. The sole plate 5, upon which a vacuum column 6 is mounted, can be slid across the smooth surface 2. By sliding the sole plate 5 over the cavity 4, the cavity 4 is evacuated in several steps.In an embodiment of the invention, the vacuum column 6 takes the form of an ESEM (Environmental Scanning Electron Microscope). In this way, it is possible to inspect the evacuated sample 4 with the ESEM.

    摘要: A method is described for generating EUV radiation, comprising the steps of generating a flow of a medium (39); transporting this medium through a source space (60) connected to a vacuum pump (75), and irradiating part of the medium with an intensive, pulsed laser beam (41) focused on said part of the medium, thus creating a plasma (47) which emits EUV radiation. In order to maintain a vacuum in the source space and to prevent elements of the medium, like vapor or elementary particles, from leaving the source space through apertures (63, 64) provided in the wall of the space for passing the laser beam and EUV radiation, the flow of medium is embedded in a flow of rare gas. The invention also describes an EUV radiation source unit for performing the method and the application of the method in the manufacture of devices like IC devices, and in a lithographic projection apparatus.
