  • Abstract
    A new method for plasma-CVD chamber cleaning using gas circulation has been developed. Unused gas contained in the exhaust gas during chamber cleaning was returned to chamber, and it was reused. Using this method, approximately 50% reduction of the amount of C2F6 used and net PFC emissions could be achieved without increasing the cleaning endpoint time
