WebAs feature sizes continue to shrink, low k1 lithographic processes are required to advance chip technologies. To achieve actual gains in resolution, both the advances in optical systems and imaging capabilities, as well as the improvements in EUV materials and photoresists are key. WebWhen adding these transition events, the curves shift to the right and are more skewed. - "What We Don’t Know About EUV Exposure Mechanisms" Fig. 8. The improvement in the model to track transitions below cutoff energies pushes the energy loss event profiles deeper into the film. When adding these transition events, the curves shift to the ...
WebContinued momentum in the development of EUV photolithography toward high volume manufacturing has increased photoresist purity requirements that accelerate improvements in resolution, sensitivity, and line edge roughness. Previous research indicates 1,2,3 that the composition of photoresist materials is a major contributor to stochastic effects as … WebJan 1, 2005 · A resist modeling technique using a resist point spread function has been shown to have good agreement with experiments for certain EUV resists such as Shipley EUV-2D [2]. The resist point spread function is a two-dimensional function that, when convolved with the simulated aerial image for a given mask pattern and applied to a …
