ABSTRACT:
Methods to at least partially compensate for photoresist-induced spherical aberration that occurs during mask imaging used for photolithographic processing of semiconductor devices, LCD elements, thin-film magnetic heads, reticles and other substrates including photo-defined structures thereon are disclosed. A photoresist or other photosensitive material may be irradiated with a mask pattern image including a selected nonzero spherical aberration value to compensate for photoresist-induced spherical aberration.
