发明名称 Vacuum processing apparatus
摘要 To improve an actual exhaust speed, in a vacuum processing device for processing a work located in a vacuum processing chamber by using a processing gas introduced into the vacuum processing chamber, the vacuum processing device having means for introducing the processing gas into the vacuum processing chamber, means for controlling a gas flow of the processing gas, and means for exhausting the processing gas after the work is processed by the processing gas; the exhausting means comprises an exhaust pump, a buffer space extended in a direction substantially perpendicular to a center of the work with an extended area larger than a size of a suction port of the exhaust pump, and a gas outlet formed on a back side of a surface of the work to be processed, the gas outlet having a size substantially equal to or larger than the size of the suction port of the exhaust pump. Further, the exhaust arrangement can be provided at a shifted position so as to allow a work space beneath a work table.
