Apparatus and method for characterizing an image system in lithography projection tool
摘要:
A system and method for characterizing an imaging system causes a diffraction image indicative of a test structure having a generalized line-grating to be formed and then extracts from a measurement of the diffraction image a lens transmittance function, a photoresist property or a defocus distance.
