Web7 apr. 2024 · All these challenges are mainly driven by lithography. With the development of advanced photoresists (PRs), the resolution factor K1 in projection lithography reduces from 0.66 to 0.39, improving the resolution by 40% without the negative impacts on the depth-of-focus (DOF). WebIn the k1 regime down to 0.5, dense and isolated features could be printed in one with acceptable process windows. Today advanced lithography is operating at k1 values of 0.42-0.37 using KrF excimer laser light sources at a wavelength ( (lambda) ) of 248nm.

Web12 mrt. 2008 · Current consensus is to employ computational lithography to meet wafer CD uniformity (CDU) requirement. Resolution enhancement technologies (RET) and model OPC are the two fundamental components for computational lithography. Today's full-chip CDU specifications are already pushing physical limits at extreme lithography k1 factor. WebClearly, a high-contrast resist increases the resolution of the entire lithography process by reducing the parameter k1 in ( 2.1 ). Typical values for range from 2-3.
