摘要： An improved oblique viewing microscope system including a diffraction grating that oscillates in the plane of the grating and/or an illuminator that oscillates the light rays directed to the object synchronized with the grating period. Additionally, a low frequency diffraction grating is also disclosed. The oscillation and/or low frequency grating provide a high resolution, multi-color image of an object viewed at an oblique angle. A dual oblique viewing microscope system is also disclosed to provide Koehler illumination.

摘要： A lithographic mask is illuminated with light from different directions such that intensities of a plurality of incident beams of light provide a largest possible integrated process window defined in terms of an allowed range for defining shapes. Constrained sets of intensity parameters are imposed. A first set of intensity parameters represents maximum possible intensities that can be permitted for overexposed tolerance positions. A second set of intensity parameters represents minimum possible intensities that can be permitted for underexposed tolerance positions. Optimum source intensities of incident beams are defined using a linear program and constraints. The optimum source intensities maximize an integrated range of dose and focal variations without causing printed shapes to depart from the allowed range. Apparatus are detailed and variations are described.

摘要： An apparatus for polarization conversion having a light source for supplying vertically and horizontally linearly polarized light to an optical path and a parabolic mirror disposed in the optical path and proximate to the light source. In different embodiments, the parabolic mirror has a mirror coating to induce a phase shift of 0.degree., 90.degree., or an arbitrary phase shift between incident light and reflected light. A polarizer, preferably a reflective polarizer film, is disposed in the optical path for reflecting light of one of the linear polarizations and for transmitting the other linear polarization. Lastly, one or more waveplates are disposed in the optical path between the polarizer and the parabolic mirror. The waveplates have opposing segments each having axes which are antiparallel to each other for recycling the reflected linear polarization by converting it to the transmitted polarization.

摘要： An illumination apparatus including: at least two light sources, in which each of the light sources produce independent light beams; a controller for sequentially driving each of the light sources at a high power above their respective maximum rated power, to produce a respective light beam for each light source, and for leaving the remaining light sources at a low power below their respective maximum rated power, such that the time-average of the high and low power levels are set to a predetermined value for each of the light sources; and a combiner and director for sequentially combining each of the light beams from their respective light sources while being driven at high power into a common output beam with a fixed direction. Various combiner and directors are disclosed including tiltable mirrors under the control of the controller as well as optical systems.
