Latest Patents

Koen D'have holds a patent for a lithographic mask designed for EUV lithography. The patent details a method for producing the mask, as well as a method for printing a pattern using the mask. The mask features an absorber pattern that is intentionally deformed in the two-dimensional plane of the EUV mask, relative to the intended pattern. This deformation is based on prior measurements of multilayer defects on the blank, ensuring that a maximum number of these defects are covered by absorber material during the printing process. The scanner operation is modulated to prevent the pattern deformation from being reproduced on the semiconductor wafer.
