Paper Abstract
New configuration is presented for ultra-fast at-wavelength inspection of defects on multilayer mask blanks. Key ideas are detecting defects in a high NA dark-field observation by using a Schwarzschild objective, sub-micron resolution 2D imaging of mask surface on a detector, and large etendue illumination by using a laser-plasma source. Expected time for inspecting a whole mask is shorter than 2 hours.
