Abstract
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 9 Elsevier Science S.A. All rights reserved.
