Book Synopsis Combining Monte Carlo Transport and Level Set Surface Evolution for Modeling Vapor Phase Deposition of Thin Films Over Sub-micron Features by : John Lewis Smith

Download or read book Combining Monte Carlo Transport and Level Set Surface Evolution for Modeling Vapor Phase Deposition of Thin Films Over Sub-micron Features written by John Lewis Smith. This book was released on 2014. Available in PDF, EPUB and Kindle. Book excerpt: A hybrid scheme is used to model the vapor phase deposition of thin films at the feature scale. The transport of the chemical species to the substrate surface is modeled with a Collisionless Direct Simulation Monte Carlo (DSMC) method. The Level Set Method is used to model the growth of the thin-film on the substrate. The convergence criteria for these methods were not found in literature. The governing equations for the Level Set Method are, in general, non-linear partial differential equations. The coupling of the DSMC Method with the Level Set Method results in a set of non-Gaussian stochastic non-linear partial differential equations. Developing general convergence criteria proved exceedingly difficult, and only qualitative results are presented to support our convergence criteria. Simulation results are in qualitative agreement with experiments and other results from literature.
