Abstract
A vacuum processing apparatus includes: a vacuum processing chamber for processing a target object; a processing gas supply source for supplying a processing gas by which a process is performed to the target object in the vacuum processing chamber; a processing gas supply pipe for supplying the processing gas from the processing gas supply source into the vacuum processing chamber; and a pressure reducing valve for keeping the gas supply pipe at a lower pressure than the atmospheric pressure when the processing gas is to be supplied to the vacuum processing chamber.
