| Résumé |
|
Microwave plasma assisted chemical vapour deposition of CH4/N-2 gas mixture using an additive solid silicon is used to synthesize SiCN. To better understand the mechanisms involved, species such as C, Si, NH, CN, C-2 and N-2 are observed by means of optical emission spectroscopy. In situ Fourier transform infrared spectroscopy (FTIR) is used as a plasma diagnostic and CH4, NH3, HCN and C2H2 have been detected. Deposits are achieved at various CH4 ratios (1, 4 and 8\%) and analysed by means of scanning electron microscopy, energy dispersion X-ray spectroscopy and FTIR spectroscopy. Adding a silicon source permits to obtain thicker layers confirming the major role of Si in the carbonitride deposition process. Deposits obtained at 8\% of CH4 have a composition about 35\% of Si, 30\% C and 30\% N and showed evidence of ternary SiCN system.
