As a result, the pressure adjustment time becomes longer. If the pressure is set too high, the increase in the natural oxide film cannot be sufficiently suppressed. For example, if the pressure in the boat loading step is set to a relatively high pressure, atmospheric pressure (approximately 10 13 hF a), This takes time to adjust and has an adverse effect on the throughput, and the natural oxide film is not sufficiently suppressed. Therefore, the waiting room in the port loading step 3

If the pressure is set to a pressure lower than the atmospheric pressure, and preferably 300 Pa or less, the pressure adjustment time from the boat opening step to the processing step should be set to a time that does not affect the throughput. In addition, the formation of a natural oxide film can be sufficiently prevented. In short, it is desirable to set the pressure in the standby port and the processing chamber in the boat port—the loading step to be 200 Pa or more and less than the atmospheric pressure, and preferably set to 200 Pa or more and 300 Pa or less.
