Web2 jan. 2024 · The fundamental equation of lithography is that the resolution (half-pitch this time) is k 1 × λ ÷ NA where: k 1 is the Rayleigh parameter, which is a measure of the lithography complexity. Yield is affected if it drops below 0.65 and then we need to do something about it (what, we will get to later).

Webresolution of lithography has become the core challenge for integrated circuits manufacturing. The theoretical resolution can be calculated using the Rayleigh equation: irradiation of UV light, the graphics on the mask plate are R=k1 (λ / NA)=k1[λ / (n·sin θ) ] In the equation, the parameter of R is theoretical

WebDue to similarity in name and nature, depth of field (DOF) and depth of focus are commonly confused concepts.
