Lithographic reticle limit
Websimulation. The impact of reticle corner rounding on the printed wafer patterns will be examined for conventional and attenuated phase shifted contact holes of various pitches. Results from this work will be used to predict the acceptable amount of corner rounding on the reticle, and to define the proper metric of reticle shape. Finally, the WebA method and apparatus are provided for measuring the apodization of projection optics for use in a lithographic apparatus, the projection optics having an object plane where, in …

Webk1 is a factor that accounts for the processing characteristics such as the quality of the resist and the use of resolution enhancement techniques like off-axis illumination. k1 has a theoretical minimum of 0.25, although values below 0.3 are considered too difficult or expensive for common use.
WebThe physical limit lithography is k 1 = 0.25. Smaller critical dimension can be achieved by using a combination of smaller light wavelength and larger numerical aperture (NA), … WebExtreme ultraviolet (EUV) lithography is a leading contender for the commercial mass-production of several generations of computer chips within the current decade. The widespread adoption of EUV lithography has been delayed by the limited light-source power and the unavailability of defect-free masks. The creation of production-quality masks ...
