摘要: An operating ratio is improved in a vacuum processing apparatus to which plurality of transfer chambers are connected through intermediate chamber. In method the having chamber and vessels chambers, respectively, made communicate chamber, purge gas supplied lock an inside far from decompressed/exhausted, pressures all raised be higher than pressure vessel.
