Abstract:
1. A vacuum processing apparatus comprising: plural processing chambers, each processing chamber having a sample table disposed inside thereof which supports a sample to be processed, the sample being processed on the sample table in the processing chamber with a gas which is supplied thereto using a plasma generated in a depressurized space inside the processing chamber; a transfer chamber which has a polygonal planar shape and is coupled to the plural processing chambers with respect to at least one side of the polygonal shape, the transfer chamber enabling receipt of the sample and transfer of the sample to and from a respective one of the plural processing chamber under a vacuum pressure; a transfer robot disposed in the transfer chamber which transfers the sample held on an arm of the transfer robot between the processing chamber and the transfer chamber; a mass flow controller for supplying gas to the each of the plural processing chambers; a connector portion between the mass flow controller and a building in which the apparatus is installed for supplying utilities including at least one gas to the mass flow controller; and at least one of the plural processing chambers comprising: at least an upper member and a lower member, the lower member being disposed in a lower portion of the processing chamber; the upper member being disposed on an upper side with respect to the lower member, the upper member being configured as at least one member which is separate from the lower member and detachable from the lower member, at least the upper and lower members constituting the processing chamber; an exhaust opening disposed below the sample table through which the depressurized space inside of the processing chamber is exhausted; at least one of hanging beams disposed with respect to the processing chamber, an upper portion of the hanging beam being coupled to the upper member of the processing chamber and a lower portion of the hanging beam being coupled to the sample table, the hanging beams suspending the sample table above the exhaust opening inside the processing chamber; and a gate which is disposed between the processing chamber and the transfer chamber and communicating therebetween, the sample held on the arm of the transfer robot being transferred between the processing chamber and the transfer chamber through the gate; wherein the upper member coupled to the at least one of hanging beams is configured so as to be movable in an upper direction away from the lower member and rotatable around an end portion of a transfer chamber side of the upper member.
