Lithography illumination
WebIllumination system is one of the most important parts of the micro-lithography object lens. Its performance can greatly affect the lithography machine's etching graphic quality. In this paper, we discuss a DUV micro-lithography illumination system which can achieve high uniformity and a large illuminated area on the mask. WebIn photolithography, off-axis illumination is an optical system setup in which the …

WebLithography for the next generation of integrated-circuit manufacturing at the 3 nm node requires sub-1-nm misalignment measurement accuracy, which is almost impossible for existing systems due to the optical diffraction limit. Herein, we propose a misalignment sensing strategy based on structured illumination. By virtue of the distinctive modulation …
