Witryna1 mar 2024 · According to the Rayleigh equation, the resolution R of the optical expose system can be formulated by (1) R= k 1 λ n sin θ = k 1 λ NA where λ is the wavelength, θ is the limiting angle of the lens, n is the index if refraction, NA is the numerical aperture of the imaging system. Immersion lithography increases NA by inserting a high index ... WitrynaAs the critical dimension of integrated circuits is continuously shrunk, thick mask induced aberration (TMIA) cannot be ignored in the lithography image process. Recently, a set of pupil wavefront optimization (PWO) approaches has been proposed to compensate for TMIA, based on a wavefront manipulator in modern scanners.
