TīmeklisWe present a lateral shearing interferometer suitable for high-NA EUV wavefront metrology. In this interferometer, a geometric model is used to accurately characterize and predict systematic ... Next- generation EUV exposure tools will have numerical apertures (NA) exceeding 0.5, providing an ultimate resolution below 8 nm. However, … Tīmeklis2024. gada 20. apr. · Metrology of EUV optics is typically performed in vacuum. This is absolutely necessary for at-wavelength metrology, since EUV light does not propagate through air, and greater precision is possible in vacuum at optical wavelengths due to elimination of air turbulence-induced measurement noise.
