Abstract:
A vacuum processing apparatus for a semiconductor process, comprising:a process container forming an airtight process chamber, and comprising a container main body and an upper cover detachably disposed on the container main body; a supporting member configured to support a target substrate in the process chamber; a gas supply system configured to supply a process gas into the process chamber; an exhaust system configured to exhaust the process chamber and set the process chamber at a vacuum; and a detaching device configured to attach/detach the upper cover relative to the container main body, the detaching device comprising a rotational mechanism configured to rotatably support the upper cover, an up-and-down movement mechanism configured to support the rotational mechanism and the upper cover to be movable up and down, and a lateral movement mechanism configured to support the up-and-down movement mechanism, the rotational mechanism, and the upper cover to be movable in a lateral direction, wherein the lateral movement mechanism comprises a pair of guide rails extending in the lateral direction and disposed parallel to each other with the container main body interposed therebetween, the pair of guide rails being configured to allow the upper cover to be moved up to a retreated position where the upper cover does not interfere with the container main body when the upper cover is rotated by the rotational mechanism, and each of the guide rails comprises a primary portion facing a side of the container main body, and a secondary portion extending beyond the container main body in the lateral direction, the secondary portion being foldable toward a side of the container main body.
