Abstract

Significant advances have recently occurred in the development of optical wavelength engineering (Modified Illumination, Phase Shifting Masks (PSMs), Spatial Filters) allowing the extension of Optical Lithography to 0.25μm design rules and below. This paper will discuss recent progress in the development of PSM technology for 0.25μm lithography using I-line or DUV exposure systems.
