  • High temperature chemical vapor deposition of SiC Applied

    A growth process has been investigated for the epitaxial growth of silicon carbide. The technique can simply be described as chemical vapor deposition (CVD) at high temperatures hence the name high temperature CVD (HTCVD). The growth process however differs greatly from that of the CVD process due to the significant sublimation and etch rates at the extreme growth temperatures (1800–2300°C).
