Chemical vapor deposition of SiC epitaxial reactor is studied experimentall
y and numerically. It is shown that gas phase formation of Si-droplets decr
eases deposition rate due to significant losses of Si. The gas phase nuclea
tion changes C/Si ratio over the wafer and results in saturation of depende
ncies of the growth rate on supply of silane and propane at the values of C
/Si ratio different from 1. It is found that effect of thermophoresis resul
ts in preventing Si-droplets from reaching the growing SiC surface. (C) 199
