SF6 Decomposition Liquefaction System for Mitsubishi

SF6 Decomposition Liquefaction System for Mitsubishi

A process for cleaning a deposit from an interior surface of a processing chamber includes generating a plasma from a cleaning gas including SO 2 F 2 and contacting the interior surface with the plasma for a time sufficient to convert the deposit into a volatile product, thereby cleaning the deposit from the interior surface, in which the process is conducted in the absence of sf6 gas .
