WebJan 1, 2014 · Phase shift mask is designed to represent a phase shift of π. In the case of phase shift lithography, mask pattern’s height is predicted with the value of wavelength of used light, refractive index of mask material. Height of mask patterns is calculated by the equation below [ 1 ]. h = \lambda / (2\Delta n) WebJul 1, 1991 · The authors report on the performance of a scanned laser mask lithography system optimized for printing multilayer phase-shift masks. This system leverages the sub-half micron printing performance of the ATEQ CORE-2500 combined with an optical alignment system. The use of 363.8 nm exposure wavelength offers significant …
