WitrynaImage contrast is limited by the inherent numerical aperture of a water based immersion lithography system. Elements of resist design and processing can further degrade … WitrynaIn this paper we discuss the results on imaging and overlay obtained with immersion. Using a 0.75 NA ArF projection lens, we have built a proto-type immersion scanner using TWINSCANTM technology. First experimental data on imaging demonstrated a large gain of depth of focus (DOF), while maintaining image contrast at high scan speed.
Witryna27 lip 2024 · The NA variations are from 0.85 to 1.25 in immersion lithography, which correspond to 0.59 to 0.87 in dry lithography. The line size variation is from 90 to 140nm for dense lines (L=S ¼ 1) for conventional illumination and from 80 to 140nm for dense lines for annular illumination. A higher NA enhances the image contrast and NILS, and Witryna1 lip 2024 · A computational method based on a constrained optimization solution is proposed using a self-designed optical model of a zoomed system incorporating axicon lenses, and a series of computations are developed and discussed.
