Industries Served


We have a strong legacy of supporting the semiconductor equipment and integrated-circuit (IC) manufacturing industry with our software products, databases, and consulting projects.  Several leading semiconductor manufacturers use our non-equilibrium plasma modeling tool VizGlow to help them analyze existing equipment, improve processes, and develop new equipment concepts.  IC manufacturers use our software to optimize their fabrication processes, identify/rectify process anomalies, and also design new equipment for their needs.

Our fast reactor modeling tool ChemZone has been used to rapidly explore large process parameter spaces in semiconductor manufacturing and also for the development and validation of new finite-rate chemical kinetic mechanisms process plasmas, combustion, and other gas chemical kinetics.

We have supported this industry with numerous consulting projects, software licensing and training arrangements over the years.

Flat Panel / Display

The flat panel / display industry uses our plasma (e.g. VizGlow), electromagnetics (e.g. VizEM) as well as fluid flow / particle modeling (e.g. VizFlow and VizGrain)  software.  Industrial clients in this domain have worked with us through software licensing and consulting projects to help them analyze existing equipment design, improve processes (e.g. process uniformity, throughput, film quality, etc.), and develop new equipment concepts.  The large equipment sizes, e.g. for Generation 10 panels, are especially difficult to design and computational modeling/simulations can play a particularly important role in the development of these systems.  The large process equipment sizes translate to large-scale simulation problem sizes and therefore especially difficult and time-consuming to model.  Such problems have benefited tremendously from the large-scale parallel computing capability built into all of our multi-dimensional simulation tools.

Solar Cell Fabrication

We have a strong history of working with many of the biggest US solar cell manufacturers in helping them design their solar cell fabrication equipment.  The manufacturing problems faced by this industry are similar to the flat panel / display industry, i.e. large process equipment sizes that translate to very large simulation problem sizes and therefore especially difficult and time-consuming to solve.  Correspondingly, these problems have benefited tremendously from the large-scale parallel computing capability built into all of our multi-dimensional simulation tools.  For this industry in particular, we have strong background in the helping with the design and development of thermal evaporation sources (for CIGS thin film system) and magnetron sputter systems (e.g. for interconnects and metal films).


The automotive industry benefits from our expertise in non-equilibrium plasmas, thermal (arc) plasmas, electromagnetics, combustion, and heat transfer.  The regulation mandated move towards low-emission, lean-combustion and smaller displacement high-pressure combustion engines has motivated the industry to rethink existing combustion strategies.  Correspondingly, combustion ignition has now emerged as a major problem for these new systems.  Our simulation tools (e.g VizGlow, VizSpark, and ChemZone) have been used in the analysis and design of existing spark-plug designs, design of next generation spark-plugs, and next generation, unconventional, plasma-combustion ignition systems.  We have worked extensively with the industry through a number of consulting projects and software licensing agreements.

Electrical / Industrial

We work with electrical and other industrial manufacturers on the high-fidelity modeling/simulation of electrical circuit-breakers, electrical switch-gear, plasma welding and cutting tools, arc lamps, plasma torches for spray coating, etc.  Our simulation tool VizSpark has in particular been used to address the simulation needs for the above applications.  For example, circuit breaker problems are characterized by a strong multi-physics nature with arc physics, self-induced electromagnetic fields, high Mach number gas dynamics, heat transfer, material ablation, and moving body within the domain.  The VizSpark simulation tool is uniquely capable of addressing these problems in a robust manner with full fidelity to the actual physics occurring in the problem.

Oil / Gas

Oil and Gas industry applications are strongly multidisciplinary drawing principally on our expertise in chemically reactive flows, heat transfer, and electromagnetics.  Our  fluid flow solver (e.g. VizFlow) is used in the flow analysis through pipes, valves, and oil/gas flares. Our chemical kinetics development capability using (ChemZone) benefits the industry through its used in the development of combustion mechanisms of complex fuels.  Over comprehensive suite of electromagnetics solver benefits a variety of applications such as remote sensing and inverse problems of interest to this industry.

Aerospace / Defense

Aerospace applications are strongly multidisciplinary drawing on almost all the areas of our expertise.  Our fluid flow solver (e.g. VizFlow, VizGrain) have been used in aerodynamic analysis ranging from the low-speed (incompressible) to high-Mach number supersonic flows and high-pressure continuum flows to rare-field gas dynamics.  Our plasma solvers (e.g. VizGlow and VizSpark) in conjunction with flow solver (VizFlow) has been used in the analysis of plasma actuators for aerodynamic flow control and plasma-assisted combustion for aero-engine flame ignition/stabilization.  Our software tools are used for the analysis of discharges in micro-propulsion applications and re-configurable meta-materials for electromagnetic wave control for aerospace/defense applications.
