Paper Abstract

Low pass filtering taking place in the projection tools used by the IC industry leads to a range of optical proximity effects, OPEs, resulting in undesired characteristics of patterns projected by the scanners. Commonly used scanner imaging models are capable of capturing OPEs driven by the fundamental imaging conditions such as wavelength, illuminator layout, reticle technology, and lens numerical aperture.
