This book was released on 1997 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computer modeling of Chemical Vapor Deposition (CVD) reactors can greatly aid in the understanding, design, and optimization of these complex systems. Modeling is particularly attractive in these systems since the costs of experimentally evaluating many design alternatives can be prohibitively expensive, time consuming, and even dangerous, when working with toxic chemicals like Arsine (AsH3): until now, predictive modeling has not been possible for most systems since the behavior is three-dimensional and governed by complex reaction mechanisms. In addition, CVD reactors often exhibit large thermal gradients, large changes in physical properties over regions of the domain, and significant thermal diffusion for gas mixtures with widely varying molecular weights. As a result, significant simplifications in the models have been made which erode the accuracy of the models' predictions. In this paper, the authors will demonstrate how the vast computational resources of massively parallel computers can be exploited to make possible the analysis of models that include coupled fluid flow and detailed chemistry in three-dimensional domains. For the most part, models have either simplified the reaction mechanisms and concentrated on the fluid flow, or have simplified the fluid flow and concentrated on rigorous reactions. An important CVD research thrust has been in detailed modeling of fluid flow and heat transfer in the reactor vessel, treating transport and reaction of chemical species either very simply or as a totally decoupled problem. Using the analogy between heat transfer and mass transfer, and the fact that deposition is often diffusion limited, much can be learned from these calculations; however, the effects of thermal diffusion, the change in physical properties with composition, and the incorporation of surface reaction mechanisms are not included in this model, nor can transitions to three-dimensional flows be detected.

This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: We discuss mesoscopic models, which reflect the transport and reaction of the gaseous species through a homogeneous media in the chamber. The models include the conservation of mass and the porous media are in accordance with Darcy's law. The transport through the stationary and nonionised plasma field is treated as a diffusion-dominated flow, [60], where the metallic deposit and the gas chamber look like porous media. Based on these assumptions, we taken into account our expertise of modelling transport-reaction problems in groundwater. While solving such problems, so-called multi-scale processes and multi-physical processes arise. Conventional treatment of black-box discretisation and solver methods are impossible or complicated. We contribute physically motivated methods, with respect to decomposing processes for simpler-coupled ones. The idea of integrating one-dimensional analytical solutions of simpler equation systems and additionally iterative solver methods to couple the simpler equations leads to so-called iterative operator-splitting methods. We present so-called decomposition methods, which decouple the different scales and solve the equations based on scales with each other. Therefore, the previous coupling errors between the terms of the equations can be controlled and minimised with our iterative methods. Furthermore, additional domain decomposition are used to decouple the complicate domains, and non-linear problems are linearised with relaxation schemes. Our flexible iterative operator-splitting method is analysed for time, space, and non-linear model equations. Because of reducing the tremendous splitting error with more iteration steps, the method is competitive for multi-scale and multi-physical problems.

Book excerpt: The chemical vapor deposition (CVD) process that consists of depositing coatings of silicon nitride from silicon tetrafluoride and ammonia at low-pressure is modeled in a reactor simulation. Combined effects of surface chemical kinetics, multicomponent diffusion, convection, thermal diffusion, species interdiffusion, and variable properties are included in a reactor model. Full multicomponent diffusion is included by solving the StefanMaxwell equations. Species interdiffusion and thermal diffusion are included in the energy and species conservation equations. Results are for five gas phase species with two surface reactions specified for the deposition. Distributions of radial and axial components of velocity, species, temperature, and deposition rate and deposition profile are obtained in a tube reactor. Effects of the combined transport mechanisms noted above are determined. The decomposition of NH3 into N2 and H22 retards deposition of silicon nitride and dilutes the incoming reactants. This dilution is strongly enhanced by thermal diffusion since the direction of the temperature gradient causes the light species generated by the surface reactions to remain near the surface resulting in smaller and nonmonotonic deposition rates. The effects of a ramp in the surface temperature on the deposition rate and profile and on the transport processes are also determined.
