Complete Design and Analysis Tool for CVD Reactors
Simulation is used to improve the design of CVD equipment, to reduce the need for prototyping and to answer the "what if" questions of engineers.
Using the PHOENICS-CVD software system engineers can:
- optimize CVD reactor design
- tune process parameters to improve yield
- explore new processes before equipment is purchased
- troubleshoot poorly operating processes and equipment
PHOENICS-CVD is an integrated software system designed to simulate the behavior of a wide range of CVD reactors; this involves the modeling of fluid flow and heat transfer in a multi-component gas, including both gas-phase (homogeneous) and surface (heterogeneous) chemical reactions and incorporating plasma effects.
Implementation is by means of a graphical, menu-driven, object-orientated interface, coupled with a library of generic reactor designs providing an easy route to problem set-up and modification.
