Monitoring of SiC Deposition in an Industrial CVI/CVD Reactor by In-Situ FTIR Spectroscopy

A FTIR based method was developed for in-situ monitoring the gas phase chemistry in the reaction chamber of technological scale CVI/CVD reactors. Using methyltrichlorosilane (MTS) as SiC precursor, several gaseous species could be detected including MTS, SiCl2, (SiCl3)n=1,2, SiCl4, HSiCl3, CH4, CH3Cl and HCl which, consequently, can be monitored simultaneously. First attempts have been established for derivinp arbitrary and absolute concentrations of species from emission spectra. The determined composition of the reaction mixture supports recent theoretical results of kinetic rnodelling. Using the established technique, several runs have been monitored within the SiC-CVI/CVD reactor at different stages of deposition. Unexspectedly strong variations of concentrations of most of the gaseous species have been detected whose reason is not fully clear yet. These technique will be a key element in establishing a closed loop process control

Mobile Fourier-transform infrared spectroscopy monitoring of air pollution

Fourier transform infrared spectroscopy is an efficient technique for the detection and quantification of molecules in gas mixtures. Measurement results from a mobile laboratory for ambient air analysis and for remote sensing of plume emission with the commercially available K300 spectrometer are reported. CO, CO2, NO, NO2, N2O, NH3, CH4, SO2, H2O, HCl, and HCHO concentrations have been determined with good agreement with in situ results. The on-line multicomponent analysis software is based on line-by-line retrieval and least-squares fitting procedures, including the effects of multiple aerosol scattering and cloud and rain influences
