WebThe present invention has disclosed a method for in-situ aberration measurement in an optical imaging system of lithographic tools, which comprises the steps of: imaging the reticle pattern by the beams transmitting through the reticle via the optical imaging system; using particular tools to measure plural groups of linewidths by modifying the intensity … 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.
