Modeling of Chemical Vapor Deposition of SiC
VR™ CVD SiC can be used for modeling of temperature distribution, flow, gas phase reactions including secondary phase formation, parasitic deposition and epitaxy. It is designed to aid in optimization of the the growth rate and uniformity, growth efficiency in terms of precursor utilization, uniformity of doping, mitigation of parasitic deposition. The software has been successfully applied for planetary reactors, vertical high-speed rotating disc reactors, horizontal reactors.
Software includes the following readily available chemical models:
- Epitaxial and bulk growth of SiC by CVD
- From C3H8 and SiH4 with account of generation of Si particles
- in Cl-free atmosphere
- with addition of HCl
- From C3H8 and SiCl4
- From C3H8 and TCS
- From C3H8 and DCS
- From MTS (CH3SiCl3) or MS (H3SiCH3)
- From C3H8 and SiH4 with account of generation of Si particles
- Doping:
- Aluminum doping using TMAl
- Nitrogen doping using N2 or NH3
- Aluminum and nitrogen co-doping
- Bulk growth by HTCVD (High-Temperature CVD)
- Growth of SiC from C3H8 and SiH4 with account for generation and re-evaporation of SiC particles.
For different precursors, please ask us directly. The software is constantly developing and some models can already be available or might be added.
