Latest Patents

Zernike holds a patent for a "Hybrid illumination system for use in photolithography." This illumination system features an array optical element positioned near the formation of a desired illumination field. The system expands light or electromagnetic radiation from an illumination source, which is then received by a multi-image optical element. This element forms multiple secondary illumination sources in a plane. A condenser captures the light from these sources, while an array or diffractive optical element is placed at or near the focal point of the condenser. The illumination plane created at this focal point lies within the near field diffraction pattern of the array or diffractive optical element. Notably, there is no condenser following the array or diffractive optical element. This design allows for the use of a condenser with a smaller numerical aperture than the emergent numerical aperture of the diffractive optical element, generating a desired angular distribution with minimal dependence on the illumination source profile.
