    摘要: A radial transverse electric polarizer device is provided. The device includes a first layer of material having a first refractive index, a second layer of material having a second refractive index, and a plurality of elongated elements azimuthally and periodically spaced apart, and disposed between the first layer and the second layer. The plurality of elongated elements interact with electromagnetic waves of radiation to transmit transverse electric polarization of electromagnetic waves of radiation. One aspect of the invention is, for example, to use such polarizer device in a lithographic projection apparatus to increase imaging resolution. Another aspect is to provide a device manufacturing method including polarizing a beam of radiation in a transverse electric polarization.

    摘要: A scanning-slit exposure device is provided with a radiation source (1) emitting radiation pulses through an exit window (2). An imaging system (3) images the exit window onto a surface (4) to be exposed by the radiation. The surface is scanned relative to the exit window image in a scan direction. To avoid the banding-type non-uniformities in the exposure, the device comprises a scattering element (12) which scattering element causes a blur of the exit window image only in the scan direction. The scattering element is arranged in the entrance pupil of the imaging system (3).
